    Coleman furnace problem
    I have a coleman electric furnace its in our 2003 mobile home we bought new.
    It is clicking click click and if you'll check the coming out of vent it will get cooler then it will click click click and the heat over the vent will get hot again
    I've replaced sequencher, all limit switches.Did not fix it is it the heating element clickin and making the heat get cooler and then click and get hotter>
    Could it be the relay? I don't even know what a relay does I'm just looking at the instruction booklet.Or could it be the tranformer?
    Thanks

    There is a diode on electric heaters you will see it by and hooked onto the element. These go out some times but usually don't heat at all when they do. Make sure the power is off cause it can hurt you. If you replace it yourself be sure to put it in the way the old one was. But the clicking sound you should be able to feel the relay and see if it is chattering the contacts. If so that can be the relay or a loose t-stat wire at t-stat or in the unit. Also check your line voltage connections to be sure they are tight.

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?
