Having problems with your Air Conditioners ?
Fan motor comes on, however, when a/c is turned on, breaker pops
If the unit is working fine in heat mode and in fan only mode, you have a short in the wiring going to the ouside unit. If it were a fan relay, then everytime the fan came on the breaker would trip. But either way, there is a low voltage short taking place in the unit. If the compressor was bad, the indoor unit would run fine and would only blow the breakers to the ouside unit. I had a unit last summer that did the same exact thing. After I replaced the control wiring to the outside unit, everything worked like a charm. Good luck!

I have a 2002 year model trailer, it has a Duo Therm Quick Cool High Efficiency by Dometic. Because the fan motor would not start by itself, it popped the breaker after a couple minutes the first time I turned it on this year. I took the top off the unit and give the fan a little spin and it would then run. Once again after a few minutes the breaker popped. I changed the capacitor for the fan but it does the same thing. Could it be the armature in the motor causing the problem? Any sug

I did turn it down to 74.Can you help ? THANKS
The contactor engages from low voltage power from the thermostat as does the outside condensing unit. You may have blown the low voltage transformer or have a loose thermostat wire. Check line voltage(220 volts) to the transformer. Check load voltage ... Ruud Central System Air Conditioner

The contactor is equipped with an overload relay and needs to be reset for the contactor to work. Press the reset button on the overload relay to reset it. It is usually orange or white colored button. But the biggest problem is the compressor not wo ... Air Conditioners
No A/C My unit will power on and the fan works, however when I turn it to the Cool mode I can hear a click in the unit, the cool light comes on for 5 seconds or less, then it will click again and the light will flash 9 times. The warranty on the unit is 4 years however only covers parts, labor is $90 per hour......Is it just a fuseable link/circuit breaker?
It seems that that the overload of compressor is tripping on and off, either your compressor overload is defective or the compressor itself ... Danby DPAC8399 Air Conditioner
I have a Sanyo Split System the indoor unit is a KHS0921 and the outdoor unit is a CH0921. When i first turn the indoor unit ON the fan will run for a few minutes and then go off. The outdoor unit never comes ON when there is a cll for cooling. The only way to get the fan to come ON again is to turn the breaker OFF and then back ON. The Operation loght will come ON when the fan is running but it will start flashing when the fan goes OFF. What should i look for?

Amana heat pump emergency heat comes on but blower will not start. The call for heat comes in and the heating element(s) glow red for a few seconds and then there is a "click" and the heating strips de-energize. The blower fan motor doesn't come on, however the squirrel cage fan spins freely. The heat pump stopped working several years ago, but I just used the emergency heat option for heating solution. The squirrel cage fan motor was replaced about 3-4 years ago.

Breaker breaks When my Dometic roof a/c compressor comes on during a regular cycle, it sometimes pops the breaker. I replaced the breaker but think there must be some sort of timer in the unit that allows some time to go by before the compressor comes back on. If I reset the breaker and turn the unit back on immediately, it pops again. If I wait about 5 minutes it will run ok. The amps are ok. Help.
This unit may have an internal overload mounted on top of the compressor. You would have to get to the\015\012compressor to find out and it maybe faulty. That may\015\012explain why the compressor comes on later on, this\015\012over ... Dometic Rooftop RV Air Conditioner
The compressor is working but the blower fan does not come on. checking the fan motor, the shaft that turns the fan can not be turned by hand. it seems like the motor is frozen.
Look for mud dabber nest on the fan blade, the blower wheel, on in the motor itself. Use pliers to turn the motor shaft. It should get easier after a few turns. Use your hand to rotate the shaft until the shaft is turning freely. You may need to ... Dometic Rooftop RV Air Conditioner
I have a tempstar 2000 heat pump approx 5 years old. The condenser fan blades will not rotate/operate; however, I can hear the motor hummming. When the unit is off, I can rotate the fan freely. When the unit is turned on, the fan sticks. Can anyone assist me with a DIY type fix until I can have it serviced? I think I have the same problem. The unit that I have is model CA3036VKA1 (Tempstar). I changed the motor. The old motor has 3 wires. It has a red,black & brown. The new motor(GE-5KCP39LG )t

Turned on AC was running fine. 30 minutes later began to hear a strange noise. Opened AC/Furnance closet & heard a sound best described as air letting out of a tire. It seemed to be coming from copper pipe. Minute later sound stopped & air was suddenly hot. As if AC was turned on fan not cold. Went outside & neither fan nor motor was running. Turned fan manually. Ran for about a minute then stopped. Outside unit was making what could best be described as a buzzing sound.
Hi!!\015\012\015\012This means that the condenser fan motor (outside unit) failed, this caused to build hi pressure and either activated a safety valve to release the extra pressure or blew a line and R22 Refrigerant escaped from system. ... Goodman CKL42AR42 Air Conditioner

Have Ruud Airconditioner model UAND 024JAZ when I turn unit on the compresser and outside fan motor come on but the airhandler fan does NOT. If I switch to the heater unit the fan in the airhandler comes on and off as it should. Why does it not come on and off when the AC is on ??? Thanks
The fan in the heating mode is on a differnt relay. So the fan relay for cooling is bad. Or if it a newer unit it could be a control board that has failed. But would need a model # of indoor unit to determine that. ... Air Conditioners
I thought i smelled the ordor of burnt wire coming from somewhere in the house, which I could not figure out where it was coming from. I tried to regulate the therostat and found the a/c would not come on. So i turned off the unit for a few minutes to turned it back on and all i could hear was a loud humming sound of the motor, but no air were coming out of the vents. The outside fan is moving. I wonder what could be the problem.
Sounds like a siezed up blower motor inside your furnace if you were running your air conditioner with out the blower motor it will turn everything into a block of ice at your indoor coil you need to let this thaw out \015\012i would ... Air Conditioners

I have a 561c central air unit. I just replaced the fan motor and capacitor 6 days ago. The unit ran great for just that long now the fan won't come on and the outside unit is hot to the touch, I can assist the fan and it starts and runs great until it reaches the thermostat temp. When it turns off it won't come back on. Is it the start relay switch?
Sounds like you need another capacitor since it will run if you turn it by hand to get it started. If you have a clamp on ammeter check the current draw on the fan motor. ... Air Conditioners
I have a dometic dual-therm rooftop RV air with analog thermostat. When I set the thermostat to heat, the unit will hum but the fan does not turn and no air is coming thru vents in the floor. Then unit will blow cold air (hums and fan turns) when thermostat is on cool, but it won't turn off unless I shut it off at the breaker. What could be wrong?

Furnace will not light burners and blower motor doesn't come on, but exhaust fan comes on immediately when turning furnace on. Turned on A/C to make sure blower operates and it does. The combustion chamber door says there is a red button to reset inside, but the only thing I can find is like a thermistor with maybe a button on it and it is not kicked. What should I try next?
The reset button should be a small round red button that you just push in to reset. If the induced draft motor comes on as soon as thermostat calls for heat then the next thing to check is the ignitor. It may be a hot surface or spark ignitor.It shou ... Air Conditioners
My wife turned off our A/C units acouple of weeks ago while we were away on vacation. Not they are both acting up. The fan is turning and moving air through the exchangers outside, the little red pressure switches are not tripped and the fans are moving air through the ducts inside as well. However, the air is not coming out cool enough to drop the house temp from either of the units. I tried the thermostat reset buttons, checked my filters, (they're clear) and my cooling coils are not iced over

AC unit outdoor fan motor does not come on as it should, but if I manually start the contactor relay / coil by pressing and holding the manual button on it the fan then comes on and goes off with the thermnosat; however, the air stays cool (that is blowing outside) and warm inside. The large capacitor does not look bad though.
It sounds like the contacts of the contactor are burnt/pitted. When this occurs, it can allow enough current to operate the fan motor but not enough to operate the compressor. ... Carrier 38CKC036 Air Conditioner

AC unit had a power surges from the electrical companny and now it only turns on the unit from the breaker panel but no response from the remote control. The fan comes on only when breaker is turn on.
