Question about Heating & Cooling

1 Answer

The blower will not shut off at the end of a heat cycle

The furnace does fine until the end of the cycle, the blower continues to run. If I shut the main power off and let it sit for awhile it will run through a normal cycle again until the end and the blower continues to blow. I have let it run for up to 15 minutes to see if it would shut of it would not.

The reset button near the ignitor is a high temperature limit safety switch. When the furnace gets too hot and the manual reset limit switch is tripped, it most likely goes into a 'safe' mode where the gas control is locked out electronically and the blower is made to run continuously to rid the heat exchanger of the excessive heat. This will continue until the reset is pushed and the power is cycled off. It will remain an endless cycle unless the reason for the overtemperature condition is not corrected.

Your furnace 'temperature rise' is getting too high due to a lack of air across the heat exchanger for whatever reason. Some of those reasons could be a restricted air filter or a blower motor that's cycling improperly on its internal winding thermostat. You could also have a dirty air conditioner 'A' coil (evaporator) on top of the furnace restricting the air flow. Nevertheless, you are going to have to have it serviced by a reputable service company's technician to correct what's wrong.

After one heat cycle, the blower motor keeps running, even after cool down is complete. The furnace will not refire until i turn off the power and wait about 20 minutes for a reset.


your limit switch is opening up, that causes constant fan. Check for flashing codes after flame shuts off and fan continues. Check airflow, filters, lack on return air for possible hi temp limit problems.

Carrier 58 Series Furnace Blower Motor Won't Shut Off


Yes. If the high limit is tripped, the furnace will bring on the fan continuously until the limit resets. Often, they will not reset if tripped repeatedly. If the furnace is too large for your application, you probably are not able to move enough air to keep the heat exchanger cool enough.

When the thermostat calls for heat it should run until the room reaches the temperature setting then shut off. Is the blower motor running and can you feel air coming out of the vents? It sounds like the blower is either not running or putting out enough air to keep the furnace heating. The blower moves the heat from the heat exchanger to the room, if it can't remove enough heat from the heat exchanger there is a limit switch that will shut the burner off if it gets to hot and that's what it sounds like is happening.

Furnace Blower cycles on & off


check out the fan switch on the unit and make sure that its the correct one. it should cycloe on @ 120 degrees and cycle off around 100 degrees. Someone may have put in a different one and that is not the approve one.
