Hi,

If the ignitor stays energized too long, could be a short in wiring, bad control board, bad t-stat.

Check burner orifice for a blockage like spider/web.

Thanks,
Robert

hi Robert
okay..limit switch is in and still acting up...now the glow plug will come on for 2 seconds and go out,,come on again real quick but then go out again.??i hear it clicking in the ignition control,..do you think the ignition control or the sequencers are bad.???

Hi,

You don't have any sequencers. Need to test circuit with a meter to find problem. Could be a shorted wire. Replacing parts looking for problem is wasting a lot of dollars unnecessarily.


Look closely for loose wire connections, bare spots on wire and shorts in wiring.


The components in the circuit have to receive power and keep it for designed length of time.


Only after ensuring that was happening, would it be time to start testing and eliminating components.


Thanks,
Robert

hey robert...i ended up replacing the ignition control...furnace seems to work fine with the exception of the exhausat motor continuing to run after the furnace shuts down.??any ideas what this can mean...thanks again

Booster relay, shorted wire.


Thanks,
Robert
