    The diagnostic light blinks twice on Coleman Evcon #DGAHO56BDF natural gas forced air out bottom Mobile home heater. 2 blinks is supposed to be "combustion air switch stuck closed" which is called a pressure switch in the part manual. I have replaced this switch like five times through the years. Why am I having to replace this switch all the time.

    You should check the intake & exhaust pipes to the heater to make sure they are not restricted in any way.
    If this is the furnace I think it is, often just a tap on the switch will unstick it.

Does the upper limit switch act as a breaker? Will the red button pop up only when it needs to be reset? In other words, if the red button is not popped up does that mean it is working correctly?
