Having problems with your Air Conditioners ?

My ruud deluxe 89 furnace is not working. The fan will work but does not blow hot air. When I move swith to Auto I hear the click, but nothing happens after that. I have changed the filters which were very bad and have changed the batteries to the thermostat. Van you help? I was hoping it was only a fuse or something like that. Im not sure where to find the fuse though. Thanks, Brayn

Air conditioning unit not running but fan keeps running even though thermostat is turned to off, auto, and temp set to highest position 90degrees. 3 amp fuse keeps blowing on the circuit board in the blower compartment. I replaced it 3 times then installed a new thermostat. no change. I can usually figure it out if I got a little input or direction. Any help would be deeply appreciated. I would much rather have a trained expert easily repair my hvac unit but I can only call the professionals in

I have a GE PTAC I have been working on. Our units are run by a wireless wall thermostat which sure doesnt help matters.

I read on the honeywell thermostat T8400C that if the reading went blank, try changing the batteries. The only way i see to get inside the thermostat is to unscrew a couple of screws. However, on the outside it says, "Do not remove screw". How do I change batteries on this thing without removing the screws? Beyond that, what can i check?

I have a Honeywell T8131C programmable thermostat. Our power went out yesterday, and now the "Bat Lo" won't go away. We replaced the batteries, but the "Bat Lo" indicator stayed on even after changing to new batteries. As per the troubleshooting guide, we took them out, waited an hour, and then reinstalled new batteries. Still, the "Bat Lo" indicator is still on. How do I get it to go away because I can't adjust the thermostat with it that way?

I installed a new honeywell rthl111 series in Oct. 2012. I wired the blue wire to the RC because that was how the old thermostat was wired. The heat worked all winter but when I tried to change over to cool nothing would work. I checked the schematics online and realized I should have installed the blue wire to the B. I checked the fuse in the power panel and saw I had blown it. I changed it and rewired the thermostat the correct way. I tried again and still neither the cool or heat will work. A

Totaline Thermostat. P474 1035 Batteries died while I was out of town. I thought a simple replacement would have it up and running! Screen comes on and reads the room temp just fine but will no longer turn on the a/c in any mode (manual or auto). I looked at the manual and it gives a wonderful warning "The manufacturer cannot be liable for improper operation of the thermostat if the batteries are not immediately replaced." Help!!! Is there any way to fix it? This is a time I wish I wasn't

This is a central air conditioning question. I have no power to the "battery-less" thermostat. I have two thermostats in the main house and swapped them out to see if one of the thermostats is bad, but both thermostats are working. There's just no power to the terminal in the living room. I checked the 5amp fuse to the air handler, and it's good. I checked the A/C unit outside and pressed down the contactor, the a/c kicks on. What am I missing?


Are you getting 24 volts from the thermostat to the transformer in the air handler? Sounds like the transformer in the airhandler. You can check it by taking the voltage from the R termianal to C Terminal and should read 24 volts. ... Air Conditioners
