I have a model 5030 in wall Siegler gas furnace and when fan starts it continues to run even after heat exchanger has cooled. Does it have a fan control or not ,I couldn't find one

The technician sould have replaced the circuit board with part number CESO11057-02 which contains a diagnostic LED that will blink out a code when a fault is senced. If not we have to diagnose the hard and costly way, test each circuit.

There are only a limited number of reasons why the blower would stop running, one being a bad blower relay and another being a overheating of the motor inself causing it to shut off on internal overheat. The relay is part of your circuit board and the overheat is inside the motor, both of which you had replaced. Has anyone checked for a restricted air filter or supply/return restriction? Loose wire?

I'm guessing now. Good Luck and let us know what you find.

I've got the same furnace. I had to replace the auxilary pump that moves the water to the floor drain. The pump plugs into an outlet on the furnace and even has a light switch to turn the power source on and off.
If your folks have the same set up, make sure the switch is in the ON position.
