Are you sure you got the right sequencer. How many KW of heat do you have.
I replaced the sequencer myself last year and ordered by model number of the furnace. Since then the HVAC guy has put three or four in so I'm not sure. I'm going to show my post and these replys to my furnace guy and hope he does not take offense. He shouldn't. At one point he said he was stumped and then concluded he had a bad batch of sequencers.....Are you sure you got the right sequencer. How many KW of heat do you have.
