Hi, what is happening is the unit is shutting off on high head pressure from the sound of it. Bryant units are top of the line! What you need to do is shut the main power off to unit. I dont no if you have a split system 2-part with a indoor unit and outdoor unit or a package unit all in one. It really makes no difference. Go to the outdoor coil, which is the condenser coil. Take a good water hose and wash this coil very good all around and inside where the fan motor is. These units are made for outdoor use but don't spray directly on the controls. Be careful not to mash the fins with to much pressure.If the fan motor outside is running up to a good speed, this will take care of the high head pressure, I know for a fact. Let me know the out come. If by some reason it does not cure this, we will go into it further. I will be waiting to hear from you.

Duo Therm A/C (2009 Sabre RV) won't shut off

bad compressor relay on control board. The relay is not opening the circuit, allowing the compressor to stay running when unit is turned off. This overheats the compressor and opens a thermal disk shutting the compressor off. When thermal disk cools down, the compressor restarts under load and trips breaker.

Goodman heatpump fan runs, condenser wont start

Either the condenser fan has bad bearings, or it has a defective fan capacitor.
Turn off the breaker to the outside unit.
Spin the fan blade by hand.
If the fan blade spins easily and will spin a few revolutions with no problem the fan bearings are good.
If not, replace the fan motor due to bad bearings.
I am pretty sure you fan motor is bad because with a bad capacitor the fan motor will not get up to speed and may just sit and overheat.
I'm leaning toward a bad fan motor.

A Carrier mod # 24ANA760A300 Infinity with an error code #72 high stage thermal cutout, What causes this?

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

Fan condenser unit wont run

This is usually a bad capacitor or bad fan motor. The capacitor is located inside the electrical panel on the outside unit. You can check these by using a meter that measures Mfds (Microfarads), most of the time you can visually see the capacitor swollen or blown. The fan motor can be checked by a meter that measures ohms, really high ohms are usually bad. If you can't spin the fan blade easily, then it's locked up. What usually happens, the capacitor or motor windings go bad, doesn't spin the fan blade, overheats the compressor so it kicks out on thermal protection till it cools back down, and sometimes the motor will overheat and go into thermal protection also. Just make sure you are getting the 220v to the outside unit too, but shut all power off before doing any trouble-shooting. Hope this helps, feel free to ask any questions!

Dryer tumbles, no heat, thermo fuse has been changed. Can it be the cycling thermostat or the heating element?

If you have changed the thermal fuse you may have a defective thermal cutoff (located at the top of the heater housing in the back). The thermal cutoff will come with the high limit thermostat located at the bottom of the heater and you should change both parts if the thermal cutoff is bad.
You can take both of the parts (the heater and the thermal cutoff) to a parts supplier to have them checked for continuity (they should both read "closed" if they are good).
Good luck to you!

Is there a way to test the compressor for high pressure

If you are doubting the compressor is bad,remove the lines,after the ac system is discharged,and blow threw the condenser to see if it is stopped up,and go ahead and remove the orifice tube and replace it,you will have to do these things anyway if you replace the ac compressor.Rate please if this was helpful,thank you.

Compresser overheat triping


It could be a few things that make the compressor overheat, when this happens, the bimetal thermal protector shuts it off to avoid damage to the unit.

Some of the reasons could be:
Dirty condenser and/or evaporator (if condenser is dirty or clogged up, the heat absorbed by the evaporator will not be dissipated, this will cause the compressor to overheat.)
Bad fan motor.(not blowing enough air to cool down condenser).
Bad capacitor (only if compressor fails to start right up or not at all.)
Worn coils inside compressor.
System clogged or dirty. (If the system is dirty or clogged up, the compressor's workload increases causing it to overheat.

Don't forget to rate this post, Good Luck!!

Fridge and freezer do not get cold but unit has power

Check the freezer fan to ensure it is operating. If it is and there is at least air movement, maybe cool, but not cold, first thing to check is the condenser coil located either at the rear bottom or front bottom. Make sure it is clean. Dust/dirt can clog the condenser preventing the unit from rejecting the heat. Same as with your central a/c. If the condenser gets dirty/plugged, your a/c will stop cooling. Other possiblity is the compressor is not operating. You should be able to hear it operating, will sound like a low hum with slight vibration. In the event the compressor is not operating, unplug the refrigerator, gently place your hand on the compressor, (it will be found in the rear bottom) to determine if it is warm, hot, etc. If it is hot, leave the refrigerator unplugged for 10-12 hours to cool. There is a thermal overload within the compressor to shut it down in the event of overheating. While the refrigerator is unplugged to cool, make sure the condenser is clean. Most causes of compressor overheating are related to a plugged/dirty condenser. Let me know if this helps.

Hot air comes out at all times even when i turn on a/c

I think your cooling fan (elecric) isn't working when the a/c is on. If so, The a/c pressure climbs very high and pops open the emergency pressure release to save the system from damage.

Check your cooling fan and relays, or ect, engine collant temp sensor.

You may have to add freon too.

A/C Pressure Cutoff Switch

The A/C pressure cutoff switch is used to interrupt A/C compressor operation in the event of high system discharge pressures.
  • The A/C pressure cutoff switch is mounted on a Schrader valve-type fitting on the A/C compressor to condenser discharge line.
  • It is not necessary to discharge the refrigerant system to remove the A/C pressure cutoff switch.
  • A valve depressor, located inside the threaded end of the A/C pressure cutoff switch, presses on the Schrader valve stem.
  • This allows the A/C pressure cutoff switch to monitor the compressor discharge pressure.
  • When the compressor discharge pressure rises, the switch contacts open, disengaging the A/C compressor. When the pressure drops, the contacts close to allow operation of the A/C compressor. For specifications regarding operating pressure(s), refer to Section 412-00 .
The switch contains a second set of electrical contacts used for high-speed cooling fan control.
  • When the compressor discharge pressure rises, the contacts close and engage the high-speed fan control. When the pressure drops, the contacts open and the high speed fan control is disengaged. For additional information, refer to Section 303-03 .
