If it's a thermal cutout that's mounted on the circuit board you may have to replace the whole board. I don't have the carrier error codes at hand. But a "thermal cutout" is normally found on the compressor. One advantage of the old (before digital) systems is that the controls were all separate. So you could replace a bad high pressure switch or contactor. Without having to replace a expensive circuit board that held most of the controls.
Not to mention being easy to damage by power surges and lightning

SOURCE: carrier 48NMX042 IFM wont stop, condenser fan motor and compressor wont run

Ok first thing is it sounds like a wiring problem. So first step is to make sure the thermostat is properly connected. Which... the main thing here is there needs to be 24v dc power coming from your control board (transformer) going to the thermostat..generally that is the red wire. All the thermostat does is connect that "red" wire (power) to one of the other wires to complete a circuit. So make sure you have 24 volts... (generally about .5amps) . if you have power than switch thermostat to fan only should energize the green wire only. then switch to ac and move temp low enough that the ac should turn on and that should energize the yellow wire. for sure one of those wires is incorrect now or the fan wouldn't be on OR THE THERMOSTAT IS NOT CONNECTING THEM AND IT IS BAD. Now about the compressor and fan.... those same wires run out to the compressor unit... ok the yellow for ac.. greeen does not go to compressor unit that is for fan only (vent).. red carries the same 24 volts... one difference here is that most carrier units only have the one transformer....so you run the red wire is the +pos 24 volt..and then a "common " wire is needed which is the Ground or neg... that wire on a carrier is brown usually but could be different depending installer. The orange wire goes to the pump reversing valve it is always energized when on ac mode...when heater is on in the winter it is heat pump and is not energized so just connect the orange and yellow together... tell me more specifics if this doesn't help and i'm sure I can help you... thanks Chuck

First, I would not advise anyone to use water around electricity!!!, And what you are doing by hoseing down the condenser coil is transferring more heat, what it sounds like is that the unit is to small for the space you are trying to cool, rule of thumb is one ton of air (12,000 BTU) to every 450 square ft of space. So a 16000 sq ft home would require a 4 ton A/C system.
Also, the unit will work harder in the daytime , during the hottest part of the day, because there is more heat load on the unit. Check your insulation in your attic.
Some other causes of this problem are low on charge, or a leak in your system, will also get worse as your system will go flat.
A dirty condenser coil, you can turn off Electricity to unit , spray down coil w/ 409 cleaner and hose off, then turn back on, a dirty coil will stop transfer of heat and make your system work harder.
A dirty air filter will also cut down on cooling, if you can't get air into the system, you can't get it out!!
Start w/ your filter, then wash your coil (outside coil) called the condenser, again make sure power is off first!!
If you still have a problem, call a service tech, preferably not the guy who told you to water it!!
HOPE THIS HELPS!!

I have no cold air in my refrigerator or Freezer. It defrosted everything.


Condenser Coils are Dirty
If the refrigerator is not cold enough the condenser coils may be dirty. The condenser is like a radiator and must stay clean in order to dissipate the heat which was removed from the inside of the refrigerator. As the coils get dirtier the refrigerator becomes less efficient, which makes it work harder to cool down. If the coils are dirty enough, the unit will never be cold enough and will not be able to cool the inside of the refrigerator to the proper temperature.
Evaporator Fan Motor
If the refrigerator is not cold enough, the evaporator fan motor might have failed. Every refrigerator has a set of coils called an evaporator. The refrigerator may have one or more evaporator fan motor(s) depending on the model and evaporator locations. The evaporator fan motor circulates the cold air from the coils thru the compartment. If there is only one evaporator it is in the freezer side. If the fan is not working, no cold air will get to the refrigerator compartment. The freezer may still get cold.
Condenser Fan Motor
If the refrigerator is not cold enough there might be something caught in the condenser fan motor blade, or the condenser fan motor might be defective. The condenser fan motor draws air over the condenser coils to cool them. The condenser fan motor is located underneath the refrigerator near the back. Pull the refrigerator out from the wall and remove the access panel to access it.
Start Relay
If the refrigerator is not cold enough, the start relay may be defective. The start relay is a small device mounted to the side of the compressor. It provides power to the run winding along with the start winding for a split second at start-up to help get the compressor started. If the start relay is defective the compressor may run intermittently or not at all and the refrigerator will not get cold enough. The start relay should be replaced if defective.
Temperature Control Thermostat
If the refrigerator does not get cold enough the temperature control thermostat might be defective. The thermostat allows power to flow through to the compressor, evaporator fan and condenser fan. If the cooling system fans and compressor are running, but the refrigerator or freezer is not cooling correctly check for an airflow or defrost system problem.
Start Capacitor
If the refrigerator isn't cold enough the compressor might be having difficulty starting. The start capacitor serves as a battery to give the compressor a little boost during start-up. If the start capacitor is burned out the compressor might not be able to start and run as often as it should. Test the start capacitor first with a capacitance meter, they don't fail often. If it's defective, replace it.
Thermistor
If the refrigerator is not cold enough the thermistor might be defective. The thermistor is a sensor which monitors the air temperature. It is connected to the control board. If the thermistor is defective the refrigerator does not cool or may cool continuously.
Temperature Control Board
If the refrigerator is not cold enough the temperature control board might be defective. The temperature control board provides the voltage to the fan motors and compressor. These boards are often misdiagnosed. Check all other components to be certain this is the cause of the problem.
Compressor
If the refrigerator is not cold enough, the compressor might be defective. The compressor is a motor which compresses the refrigerant and circulates the refrigerant through the evaporator and condenser coils. There are several other components which are more likely to be defective if the compressor doesn't work. If the compressor itself is defective a licensed professional will need to replace it.
Main Control Board
If the refrigerator is not cold enough the main control board might be defective. This is not common. Check the defrost system, cooling fans, and cooling controls first.

Freezer in defrost to long


The motherboard determines the defrost time and how often, but I don't think it is the most likely reason for what appears to be a extended defrost. Sometimes the start relay, overload and run capacitor fail causing the compressor to short cycle. Sometimes the whole problem is caused by a defective condenser fan motor that stops and runs or runs poorly causing the compressor to overheat.
Here are the parts=> WR62X0079 Run Capacitor
WR08X10025 Overload
and the WR07X10084 Start Relay

The condenser fan is=> WR60X10220 Condenser Fan Motor

Car runs hot when idling


Make sure the electric cooling fan(s) for the radiator are working.
TEST- anytime the air conditioning compressor kicks in, so should the cooling fans. Locate the a/c compressor on the engine, it's belt driven. Start the car and with the engine running observe the face of the belt pully on the compressor while an assistant turns on the a/c in the car (defrost feature on your heater control will also cycle on the compressor). You'll be looking to see that the front of the compressor pully starts spinning when the a/c or defrost is engaged. When that pully starts spinning the radiator fans are supposed turn on at the same time. If you see the compressor engage but the fan doesn't you have a blown cooing fan fuse, bad fan motor or a bad fan motor relay. If there is something wrong that your compressor isn't engaging in a/c or defrost and the fuses are ok, you're going to have to check the fan motor and relay by different means. You can disconnect the wiring plug to the fan motor. This is where you see if you can spin the fan blades by hand. It should spin very easily. If it is hard to spin or is siezed up, you found the problem. If the blades spin easily- direct jump current to the fan motor off the battery. If the fan doesn't work, replace it. If the fan works, check the relay. Locate the fan relay and look for another relay in the panel that is EXACTLY like it. WE WANT- another relay that is exactly the same BUT NOT critical for engine or a/c operation. We also want to know that whatever feature this candidate relay supplies power to is verified as functional. Swap the relays. If the fan still doesn't engage, check the function that you borrowed the relay from and verify THAT works with your original a/c relay in it. If you lost that function, try the proceedure with a 3rd relay if possible. Again check and recheck functions you borrowed the relay from. If you still get nothing, put the relays back to original placement. If you still are getting nothing from the fan and the other 2 functions, then the panel is toasting relays and you need either run the problem down or get the car into a professional. Now- if the fan won't engage but the other functions that you borrowed relay(s) from are still operational, we're going to give the relays a passing grade and it would seem you've got an electrical issue that, again, you need to run down or defer your efforts to a professional. Good luck on your endeavor.

Rangemaster sxs cream . Why is my fridge and freezer the same temp ???? If anybody could give me an answer or solution.


Jason,
MOST refrigerators get there cold from the freezer side and circulate it via a fan that's also normally inside the freezer. There are three motors normally in a refrigeration system. The inside Evaporator fan motor that circulates air across the evaporator coil inside the box, the Condenser fan motor near the compressor that cools the freon after compression, and the compressor itself. If you open the doors (and sometimes you may have to hold in the door switches) do you hear a fan running? If not you could have a couple things going on: 1. The fan(s) has failed. 2. The freezer Evap coil may of iced over and the fan too is frozen stopped. 3. Your condensing unit:(compressor, condenser fan, condenser coils) has a problem.
It is important to know if the compressor itself is running. If there is a loose connection to the compressor via the start/over load relay (normally attaches directly onto the compressor), or if the start/over load otself is bad the compressor will not run. Best way to tell is via gauges but I doubt your frig has ports. Check to see if your compressor is really hot. Could be bad start/over load relay or bad compressor. Try unplugging your frig for say 30 min then, with your hand on top of a cool compressor, plug the frig back in and see if compressor smoothly vibrates for at least 5 min without becoming very hot or shutting off even though fan continues to run. The fact your fan is running TYPICALLY means the thermostat is calling for lower temps and the fan/compressor kick in together.

My GE GSL 25JFPABS Refrigerator failed yesterday. No Comressor no evap or condensor fan


Fan motor starts with the compressor. Sounds like you need a main board and condenser fan motor. Call GE. It might be covered under warranty. A known issue with certain models. You will also need serial # if you call.

Freezer cuts on every 3-4 minutes. stays on 8-10 seconds. some thawing occuring


If I understand you correctly the compressor is short cycling. The more it does this the worse it gets by causing the compressor to overheat. Sometimes the problem is because the condenser fan or evaporator fan being defective. Pull away from wall and remove cover over compressor unplug and feel top of compressor and if too hot to keep hand there keep unplugged but do examine the evaporator and condenser fan to eliminate them as a reason. The most likely reason is start relay and or start/run capacitor and sometimes a worn out compressor.

Parts in that photo are marked as 10 overload/relay, 11 is the run capacitor and 3 being condenser fan motor. Condenser and evaporator fan motors do not always stop completely when bad so make sure both run while compressor is running.

Refrigerator and freezer both are not working. fan in back of unit running but internal fan not running. i also cannot hear the compressor kicking on.


. Cut everything off for a few minutes then turn it back on and listen for a click from the compressor relay as the compressor tries to start.
Is the compressor motor running.If no check starter/overload relay.
Check to see if the condenser fan at the back underneath near the compressor is running. If no check fan.

Are the condenser coils near there warm or room temp. should be warm

It sounds like your condenser fan motor may be locked up or the capacitor that helps give the condenser fan motor a kick to get it started may be defective. Try turning your system on and using a long screwdriver try to push the fan blade on the condenser fan motor to see if it will run normally if you give it the starting boost it needs.If it does run at full speed and doesn't over heat or start and then slow down then you probably only need to replace a simple 10-12$ capacitor. If it barely turns, makes an odd humming sound or overheats etc. then you will have to replace the condenser fan motor. This is assuming that the outdoor condenser has the 220v supplied and the 24v supplied to the compressor relay, that the compressor relay is engaged and suppling 220v to the condenser fan motor.
