Having problems with your Air Conditioners ?

The furnace is blowing warm air even if the thermostat low.

\015 The furnace will not shut off unless you trip the breaker to the off position. I had not used the furnace in several weeks until this past weekend. It was working fine when I cut the furnace on and then later in the night the heat cycled on and stays on blowing warm air the termostat was set at 68 degrees with the blower set to Auto setting. The trailor home reached 80 degrees untill I had to cut the furnace off at the breaker. Can you please advise where I should start or is ther termostat bad. Thanks, Mike\015

The only thing that tells the unit to come on and off is the thermostat so I would definatly say it is it. When you turn the system back on, does the a/c run normally? If it does, then it's the problem with the heating side of the tstat. Also, does the fan come on when you put it to on and then turn of when you switch it back to auto? If it does, then the system is working fine, its the t-stat. Let me know if you have any more problems.

I have installed a UPM model THM101B thermostat on my Intertherm model E3EB-015H electric furnace. I wanted the feature of turning the blower "ON" without the heating elements. I picked up the green 12v for the fan relay. Once the power is restored the furnace comes on even though the temp setting is low and the only way I can turn the furnace off is by disconnecting the green fan relay wire? The jumper has been properly set in the new thermostat for electric furnace operation.Right now I feel t

I am trouble shooting a Bryant Hi-bred system that uses an air cooled heat pump with high efficiency gas furnace for backup and low ambient operation. How does the system decide whether to use the air cooled heat pump or the gas fired high efficiency furnace. It appears to be outdoor air temperature related, but I can't find the setpoint for it. The main zone Bryant thermostat appears to control the system, but it doesn't always bring the backup heat if the heat pump doesn't function.

I have a goodman furnace and air conditioner. When the air conditioner is running, it runs for about 10-15 minutes, then shuts off for about 5 seconds, then restarts. Could you tell me what would be wrong? I think also associated with this problem, when the heat is running, the furnace will run for about an hour, then shut down, even though the temperature has not been reached. Resetting the breaker, or depressing the reset switch in the thermostat will start the furnace running again. A third p

Over the summer we shut our thermostats off so that our furnace would not turn on since the weather was beautiful. But we noticed that our heaters in our downstairs part of our house were warm. The furnace did not sound like it was on, but for some reason, the heaters were emitting heat. In order to stop this, we had to manually shut off the valves on the furnace. This stopped the heat from coming out of the heaters. But now that it is fall, I have the thermostats on and even when the tempera

The outside compressor and fan will not shut off. I have turned the thermostat system to Off and even to heat, but it will not stop. I went on a trip, increased the room temp to 80 on the thermostat and left. When we returned 2 1/2 days later, the coils were frozen and no air was comiing through the vents, even with the blower motor working. So I turned the unit to furnace and melted the ice on the coils, but had to pull the fuses on the outside box to get the compressor to shut off. Is there a

I have an electric furnace and heat pump that will at times blow only cold air during the heating season. I have checked the filter and don't believe that to be a problem. I usually have the temperature set to 74 degrees. When the outdoor temp. is extremely cold the axillary heat indicator will be on and still no heat. I can turn the heat pump off by switching to emergency heat and will get some heat from that but not as warm as I think it should be and even that will at times only blow cool
