Thanks for the information, it helps. Is there a way to test sensors and sequencer when disconnected from furnace?

Started to not blow as hot as it used to. Is it possible coils are not getting full volt/amperage?
What would cause this to happen?

Blower has a hesitation problem when shutting down. Replaced the sequencer, seemed to work properly at first but now hesitates again.
Any ideas ?

My coleman electric furnace won't stop heating. Disconnected thermostat, no help. Had to throw the breakers. It's a 3400A818 model. Please help. I'm melting.........
