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.

Goodman model PGB036075-1B will start the gas and the burner but will shut down before blowing heat. Is it a bad switch?


Hello, sounds like either a dirty flame sensor or open limit switch. First try cleaning the flame sensor by turning power off to the furnace and using some steel wool. If the flame sensor checks out good then you limit switch is opening becuase of lack of airflow. check air filter, clean blower wheel, and check to make sure the blower wheel is running at proper speed and not dragging sometimes cause by a weak capacitor.

I would guess that the fan off setting on your limit is set a little to high. If you have the manual you can see what it says about changing the running time for the fan after the burner has shut off look on the control board and you should see two switches,one to set the time for burners to fire before main blower starts and one to set time for fan to run after burners shut off. To help with the problem you are describing set fan run time up so fan wii run longer. Hope this helps. Thaks.

Fan and heater run fine but fan does not shut off for a long time


Check the diagnostic indicator.
1. If the blower runs for hours make sure the fan switch on the thermostat is set on "auto".
2. The furnace safety system must be in lockout. This is the furaces way of telling you there is a problem.
3 Most common problem is a dirty flame sensor.

BLOWER CONTINUES TO BLOW COLD AIR AFTER REACHING DESIRED TEMP.


There is a little switch on the circuit board. Look closely at the wiring diagram and it will indicate which switch to adjust. If not, review the operating manual for details.
