What is the best way to tell whether my limit switch is bad?
The continual running of your furnace’s blower is the most prevalent symptom of a faulty limit switch. In the same way that the limit switch prevents the fan from turning on until the heated air has reached the proper temperature, the limit switch also prevents the fan from turning off until the air has cooled to a certain temperature.

What is the location of the limit switch on the furnace?
The limit switch is a safety control switch that is situated on the furnace’s lower plenum, right below it. The burner is turned off if the plenum becomes too hot, as indicated by the limit switch. Moreover, it disables the blower when the temperature goes below a specified threshold after the burner has been turned off.
What is the location of the furnace’s on/off switch?
It’s frequently fixed on the side of the furnace or on an adjacent wall to keep it out of the way. This switch, among other things, enables you or your plumber or furnace repair specialist to turn off the power to the furnace without having to travel to the main service panel and turn off the circuit breaker.
What is the best way to tell whether my limit switch is bad?
When a limit switch fails, one of the most prevalent symptoms is an inability of the blower fan to cut off. This occurs when the switch simply fails to turn off the fan after the burners have been turned off and the air exchanger has been allowed to cool enough. Furthermore, a faulty switch might prohibit a furnace from running at all.
What is the procedure for resetting a Lennox furnace?
