I had to replace a sequencer on my furnace and I rewired it according to the wiring diagram but now my furnace won't come on. Any answers as to what might be wrong with it??

did you buy the one designated as replacement for that part from a coleman distributor or did you buy a generic sequencer off the shelf ?

are you sure the heater on the sequencer is the right voltage ?

what were the symptoms that prompted you to replace it to start with ?

do you have a fuse ?

did you verify all your breakers are on ?

I bought the sequencer from a mobile home parts store. I made sure that the part number matched and took the extra step by taking the old sequencer in to make sure it matched as well. I had to replace it because part of it and some wires had melted. I was told it melted because my furnace constantly ran and never shut off. I have checked the fuse and it is fine and I did turn all the breakers on after I had replaced the part. Could it be the thermostat that has gone bad as well?

do you have a volt meter ?

will your fan run if you move it from the 'auto' position to the 'on' position ?

can you post a photo of your control panel ?
