I have a 1985 zimmer mobile home with a coleman electric furnace serial #108474059 some times when I turn the thermostat for heat the coils heat up but the blower doesn`t come on unless you tap the seqencer with back of a screwdriver any Idea which part I will need?

Thanks

The sequencer also controls the blower on most units so I would be replacing the sequencer. Taping with a screw driver was a dead give away.

Yep
