I think you have a high pressure switch that has tripped. open up the case and look for a switch connected to the line with a resettable button in the case it is not resettable you will have to have a professional replace it. If you are able to reset it make sure to clean the condensing coil on the top side before running it again as most likley this is what may have caused it to trip.

Amana Air Command 80 with fan mode is on, the furnace is running and blowing heat. Why the furnace did not do any thing when I set it on auto mode? Then I replaced a new thermostat, but nothing change


Try setting the temperature higher. It could be that the room temperature is not getting cold enough for the automatic controls to activate the heater.

Why heater fan will not come on?


Wish I knew how old your furnace is. Let me answer your question directly. In the heat mode the fan runs independently from the air conditioning fan relay. Its either brought on by time or temperature. An old furnace will use a fan and limit control that uses a coil to sense the heat exchanger temperature and turn the fan on or off. Newer furnaces use a timer on a circuit board. 20 years or newer Ill bet its a timer board. Follow the blower motor wires back to the component and ill bet that's the culprit. Hope it helps. Good luck.

Furnace will not run when hooked up to electricity


Go to your thermostat and access the fan mode. Change the fan mode to Automatic, AU. This will stop the AC fan from blowing when the furnace is turned on. If the fan mode is on Hi or Lo and the furnace is turned on it will turn on the AC blower. Bad design...

Air conditioner won't stay off


Go to the thermostat and access the fan mode. Change the mode to AU (automatic) then turn the furnace on and it should work normally. If the fan mode is in Hi or Lo the Ac fan will blow.

Pleasureway Traverse furnace fan runs when funace is off.


Bad/ stuck fan relay or temerature sensor is not shutting the fan off. Or there is a short on the low voltage fan control circuit. Check to see if the Green terminal is jumpered to the Red terminal at either the furnace control board of the 'stat, if not, ohm the wires with both ends off- I've seen installers accidently shoot a staple thru the wire and short the wires together more often than even I can believe! Hope this Helps! PS Some furnaces have fan switches inside the furnace- check for one and see if it's "on"- sounds too simple, but sometimes the "simplest" is the correct answer.

First check to make sure that you furnace filter is not plugged. Now with that being said your furnace may be working exactly as intended if the motor is staged. The way a high efficiency unit works is slowing down the fan speed to maximize heat transfer from the coil.

My guess is that your furnace is working correctly (if filter is not plugged).
