My colman furnace runs short cycle on and off every 2min replaced double stacks new thermostat still same way. How do I fix this problem

I guess it is a electric furnace?? You did not say.

Double stack?? Is this a heat sequencer??

Model number please.

Is your air filter clean ?

Are all your registers open. If this is a mobile home you cannot close registers

Yes it is electric. Double is a heat sequencer, all registers are open. Filter is clean. Furnace man was here yesterday says I need new one. Colman model#6806 for housetrailer.we just rebuilt this one before winter. Thank you hauler

Adjust the heat anticipator in the thermostat.

If you turn the fan switch to on at the thermostat and make it call for heat will it keep running?
