Having problems with your Air Conditioners ?

Fan setting only works

\015 The fan only setting on my thermostat works but when I switch the setting to auto it will not blow air through the vents.\015

Answers :

Bad thermostat or open thermostat wire can cause this condition
Air Conditioners have a fan speed relay built in the unit, faster for cold air and slower for warm heated air. It is very possible that your relay is defective

My Honeywell ducted heating at home isn't working. I have set the on/off times for the week and set it to turn on automatically but nothing happens. I think the system is connected to the gas system outside (although I'm not 100% sure) and the gas water heater works so I assume the pilot light is working OK. Perhaps the fan or the fan motor has conked out? Any advice welcome! Thanks

I have a heil -- model NUGK100DH12-- problem is when power is supplied to it the blower fan comes on right away along with the induction blower and it does have the electronic pilot which all works to thermostat setting. when setting is reached the flame shuts down normally and I think the induction motor cycles correctly, but the blower motor never cycles off. It's on constantly. I tried replacing the fan relay to no avail and am considering replacing the timed fan controller as the next move

My LG Lan125HV works fine on air conditioning ( cool) but heat pump does not trigger when I move to heat or combined settings. Tried all temperature and fan settings, tried waiting to see if unit waiting so as not to blow cold air, nothing works. Switch back to cooling and everything works fine.

I talked to LG customer support (800) 243-0000. The tech told me that this model had a problem with the indoor thermistor. It doesn't fail with an open-circuit condition, so you don't get an error code. The thermister just goes out of range and be ... LG Heat cool Window Air Conditioner

Amcoraire Bought an Amcoraire mini split ductless system in NOV 10 for a new home project we are building. I completed all the installation work and hired a HVAC technician to do the final install work. Everything went fine until we turned on the power and set the AC to the lowest setting on both units. Fans came on and louvers started working, but compressor would ramp up and run for about 30-40 seconds and then shutdown. Error code of FC was displayed on both indoor units. I called the place I

I can't get my a/c to work. I have a totaline residential thermostat P/N P374-1700. I set the thermostat to cooling only and set the temperature to 72 degrees and while the house is 75 degrees and the green light goes on, nothing happens. The fan doesn't run either. I have HVAC on both the lower floor of the house and a separate station on the upper floor. The upper floor station works. The lower floor station worked fine earlier today, but nothing now. Any suggestions.

My new Hampton Bay window fan no longer works at the highest setting. It will work on settings 1 and 2 but will stop spinning when I set it to 3. Is there a way to fix this? Thanks!

The compressor works. The fan seems stuck. If I take the covers off and spin the fan, it works. If I put the setting on auto the fan won't start up. Any suggestions?

Sounds like the capacitor for your fan is shot. This is a very inexpensive part and will cause the fan to act just as you describe. You can check it with a multimeter that has the capacitor check function. Take the old one with you to get the new one ... Coleman Mach 15 Air Conditioner

My bonaire evaporative cooler cycles from high to low fan speeds when set in the cool mode. It works fine at the required speed setting when just the fan (no water) is selected. It also dumps water immediatly the cooling cycle is turned off rather than holding it for about 40Min as it should. Sounds like a controller problem, but I'm not sure if it would be the touch pad or the board up on the roof mounted unit.

Hi Guys, I work on a mine site and the temperature on my Mitsubishi model MSZ - 25GEVA split air con has been set and I cannot change it via the remote control. In any mode i.e. cool/ heat if you push the temperature buttons nothing happens. The remote works fine ON/ Off/ Fan etc but they've locked the temperature so it can't be changed. Even if I push the reset button the temperature still remains pre set. I'm of the thought that I might need to remove the batteries and hold done specific bu

Hello. It appears that your thermostat is bad. Change it and you should be up and running again. J. ... Air Conditioners

Compressor does not run. On turning the AC on, the compressor does not run. The blower fan does though. Checking the relay panel, the relay for the compressor does not engerize. a temporary solution is to put a switch across the contacts the compressor on and then the thermostate is set so that the AC should work, the fan comes on and the unit works as usual. The only exception is that the temperature must be controlled manually.

Hi, if you are energizing the contacts on the contactor, and the compressor runs, the thermostat is faulty. This is what energizes the contactor coil that you have. You need to check to see if you have voltage to the coil on the contactor. You need t ... Coleman Mach 15 Air Conditioner

I am puzzled. Nothing was working with the Ruud unit. The fan was not coming on while setting was set to auto or on. the condenser fan was also not coming on. I traced back to the transfomer and there was no low voltage coming from transfomer though the two legs of 120v were going into the 240v and common leads. I changed the transformer with a 120/208/240 to 24v transformer and saw the same results. I thought well maybe I bought a bad transformer. I picked up a nother transformer from a

You said you have 120 vac but then you say you have it connected to the 240 v and common legs. If you have 120 v going to the transformer you should have it connected to the 120 v and common legs. Before you reconnect the transformer use an ohmmeter ... Ruud UBHC Air Conditioner

I have an LG mini split ac / heat pump system ( LAN096 ) that is only 4 months old was working great in all ways until suddenly it quit heating. I am sure it happened quickly because I was nearby when very warm air changed to cool ( unheated ) and hasn't heated since. When I shut it down and restart it the indoor fan runs right away, which is not normal and the outdoor unit will run for a minute or so then shut down and stay off. The indoor fan will continue to spin as though it is set in a 'fan
