Having problems with your Air Conditioners ?

No Power Like everyone else the unit was working fine the 1st summer. Pulled it out again and nothing. It powered up for about 30 seconds then shut down. Now no power at all to the control panel. Is there a fuse link, or some kind of auto shut off I should be looking for? I can't say if it still blows hot and cold as I can't power up to find out.

Not a GE unit. I charged unit with refrigerant and powered up unit. After running for @ a minute it shut off, having no power light at all. I found a set of wires reversed that were going to the outdoor unit. after fixing the wires i can't get the unit to come back on. The breaker is not popped and I assume there is some kind of fuse or overload that I have to manually reset or replace. It is a chinese (i think) made unit Air Control


Since most of these units, come precharged for line sets up to 125' in some models, the fact that you charged it, concerns me. Second you made no mention of the king valve, did you open it.\015\012 Then your diagnosis speaks to overvcharge, an ... GE Quiet-Aire Ductless Mini Split System Air Conditioner

Turned on the furnace last evening to warm things up. When reaching the auto, shut off temperature, the fire/heat shut off OK..but not the fan. Had to shut the power off in order to shut off the fan. What might I do to fix this problem? Is there a reset button (I didnot see one)? Thanks for any help!


Turn the syestem to off-no heat or cool and the fan to auto, turn the power back on, if the fan comes on you probably have a bad fan limit switch. ... Air Conditioners

I just moved into a new place and it has the RTH230B thermostat installed. I turned on the furnace, set the thermostat to "Heat" then the fan to "Auto" and used the up and down arrows to set the temp to 72 degrees. The temperature seemed fine for the first hour or so. However, the heat and fan stays on full power and continued to heat at full power well into 80 degrees on the thermostat screen. I could only shut it off by turning off the actual furnace switch. I first tried reducing the temper

Hurricane Gustav just blew through Baton Rouge and we were without power for over twelve hours. When our power was restored the a/c felt wonderful and we were so grateful. The a/c ran well all night and then shut off this morning around eight o'clock. Is there a way to reset the unit? We have checked fuses, the pan in the attic is empty, we tried to just run the fan, but it wouldn't turn on. Any suggestions?


Verify your outside breaker did not trip or the inside breaker. Reset once if it continues to trip have some one check it out. If you have a programable t-stat take it off the wall and remove the battery this will cause it to reset ... Air Conditioners

1989 damon escaper ultrasport, at full hookup site A/C working fine until it just shut off. At that moment I was programming fridge because it wasn't cooling. Might be irrevelant but fridge now working. I unplugged electricity from RV, turned off/on breakers - nothing. Inside RV I noticed A/C power cable in cabinets says "do not exceed circuit rating 16 amps" Im plugged in a 30amp site. Is there a fuse box for AC? Did I burn circuit? I'm a novice when it comes with RVs. Please help, thx

I was running the genarator with the a/c on and the genarator stopped with the a/c on.No power to the a/c. I plug in the motor home to 120 current and tried the front a/c and the compressor comes on without the fan when the thermostat is in off position. the only way I can shut it off is change the switch to rear air position. I check the fuses and circuit breakers and all are ok It seems to me maybe a relay is sticking. what can I do John

Why does my gas powered central heating unit blow out cool air? When the heat kicks in, there's a burning smell. Also if I set my thermostat to 77 degrees and the thermostat reads 72 degrees, the unit runs for a few minutes and then shuts off never to reach 77 degrees. Would you kindly tell me what the problem could be?


Call a service company because you should not smell anything. You may have a crack in your heat exchanger and be getting CO which can kill you. ... Goodman CKL49AR49 Air Conditioner

I have a Sharp portable room air conditioner model CV-P10NC. The power plug RESET button and TEST button will not click in order to check out the power plug as the unit will not turn on. They did test O.K. at first but the unit would still not come on.

When the AC fan shuts off, the compressor appears to be stuck. It continues to make a humming sound as though it is running. If I remove power and return power it hums momentarily and then shuts off. Is it OK to allow it to "hum"? I constantly kill the power when the fan shuts off in fear of harming the motor or compressor.


Yes, not good for compressor to stay on after being shut off, and hitting the breaker to stop it is a good idea. Sounds like you have a faulty/sticky relay. Not an expensive part, and shouldn't take any longer than 1/2 hr to change. Have a technician ... Dometic Rooftop RV Air Conditioner

I have a Carrier Heat Pump model FK4CNF003. I noted that the thermostat wasn't working (no power) so I checked the usual suspects...in bound power etc. before I pulled the top housing off the interior unit. I noted lots of wires on a circuit board in the upper right corner of the unit which seems to route power and signals to/from the thermostat. Looking closely, I noted that the 5 amp fuse was blown so I put in another 5amp fuse and it blew as well. Given the fuse is blown, and I'm assuming
