Question about Heating & Cooling

Open Question

Tempstar 5000 This spring I turned on my air conditioner for the first time and it would not start at all... The fan did not turn on either. I turned off the main 220A breaker and puller the control fuses and put everything back and the unit started working fine. now fast forward to yesterday... house started feeling warm so I did the same thing... Tripped the breaker. Pulled the control fuses, and this time made sure I had new batteries in my thermostat. Started to work again. All was good. pushing cold air out once again. This morning woke up to a house about 10 degrees warmer than the thermostat. But, the big differance from the last two events is that the fan on the unit WAS running along with the house air... is there something I can do to trouble shoot this or fix it, without spending the money for a repair man???

    Thanks to all of your for your good advise. I replace the batteries in the thermostat, really just because. Sometimes you find the little things can help. Figured I's give it a shot. I tripped the breaker manually (turned it off, turned it on) Though it does make sense with the draw in amps. My house has a 25kva Tub and I am the only one feed off of it. So sorce side of power is 123V. But just yesterday while this was going on, I noticed my lights dimming once and a while, so I am guessing that the unit is trying to draw a lot of amprage.

    The compressor is probably having a hard time starting. In thus scenario, the comp will start sometimes, and sometimes trip the breaker. This is caused by loose wire connections at the compressor, contactor, disconnect, or breakers. Also cause by a weakened start winding inside the compressor, or it starting against a near closed expansion valve. If its a loose wire, tightening connections is a cheap fix, if you're careful and experienced at this. If it's the other scenario, it may need a start assist kit installed, and that would be a service Tech's job. Also, it may be the contactor loosing connection on 1 pole, allowing the wrong voltage to feed the compressor. Hope this helps!

Remove all power from the furnace, it is likely the brain in the furnace is need of being reset, from the battery replacement, why did you change the battery, was there an indicator telling you to change it?

Many times just removing all the power to the furnace will do the trick with a reset, if not let me know and we will go from there, but it sounds like the main brain is confused or bad, more likely confused, so try the power removed first.

Than let me know

SOURCE: outside unit fan not turning no cold air inside.

Ok here we go. It is possible that the capacitor for that fan unit is out or the motor for that unit is out. Without the proper tools i.e. an electrical meter, there isn't really a way to test the unit. The remote should not have anything to do with the unit activating if the is a manual thermostat. I suggest checking to see if either the motor has gone bad or the capacitor has bit the dust. If you have the motor changed make sure to replace the capacitor

Good Luck on your repairs hope I helped you some\

SOURCE: Carrrier Central heat and air. Model 38CKC042300,

Unfortunately no, this is one of three things.
1. Compressor is worn and is starting to pull to many amps to operate. Can possibly be fixed by putting a hard start kit on the unit, but will have to be done by a technician.
2. Compressor has an internal short and will have to be replaced.
3. Fuses bad or under sized. Max fuse size is stated on information plate on outside unit.

Sorry to hear about your troubles and hope you can get it fixed soon!

Tempstar indoor outdoor central air unit is so noisy you can't hold a conversation. any lubricant's i could use and where.

I'm assuming you have an air handler that is inside. Turn the power off and make sure there is nothing that the fan is hitting. If not the bearings are probably bad. These motors are sealed and cannot be lubricated. You will need to replace the fan motor.

Why tempstar 5000 High Efficiency a/c outside fan won't turn off ?

Sounds like your contactor is sticking in your outside unit. They could be welded shut.

Tempstar Air Conditioner wont come on

Sounds like you need a new contactor in the condenser. The low voltage is grounded. Remove the low voltage (likely 2 wires) at the condenser and wire nut the wires leading inside. With an insulated screwdriver manually push in the contactor and be sure both compressor and fan run. Then replace fuse and turn power on to air handler with a call for cooling. Obviously the outdoor unit won't run because you unhooked the low voltage but if fuse doesn't trip then it's likely the contactor. Good Luck

I have a Tempstar 5000 that is about 15 yrs old and the fan motor to the outside unit will suddenly stop working and the compressor will start making a loud humming sound that does not sound too good. I...

Sounds like the condensor fan motor is going bad.If the fan stops turning or is not turning at full speed, the compressor can not give off heat to the condensor.Which will cause it to shut down on high heat.

So i would start with a new fan motor.Your local heating and cooling supply house should have these in stock.

Tempstar High efficiency 5000 losing/leaking full freon tank in

this system has to have a rather large leak. for it to loose it's charge in that short amount of time, is terrible. there are leak detectors that can sense a leak as small as 1 ounce per year. I strongly suggest you get the system leak checked before putting more "Freon" in it as it will just leak out again.

Tempstar a/c condenser screeching noise

Could be the fan motor's bearings. Try turning the fan by hand to see if spins freely or is tight. If it's tight you can try oiling it but that may not work for long.

I have an old Tempstar air condition and when I turn it on the compressor runs and the fan looks like is is wanting to turn but it quits. HELP me

Check the voltage on the fan connections. Bad connections cause resistance to current. If connections & voltage are good than the problem is probably your fan motor if its clean from dirt/grease/dust etc. Plug off the unit and try to spin fan blades with a pencil and observe if rotor is turning freely. If its spin normal than again your fan motor is not good.

If its try to spin on its own when the units turned on and creates excessive heat, this indications generally pointed an abnormal resistance problem at the circuitry or on the power consumed points of the unit.
