My fan sequencer on one of my air handlers was shot (blower wouldn’t kick on despite coils getting hot, but manually setting the fan worked fine), had to do some googling but found out this would work fine to replace my FirstCo E141 sequencer. Took about 10 minutes total to swap it out and it’s worked perfectly for a few months now. Easily saved $150+ vs having HVAC come out and do it.

I had to send back cause it makes it sound like it is going to come on at 30 seconds and shut off after 90 but it comes on at 30-90 seconds and shuts off some pitiful amount like 20 seconds. Didn’t work for me.

My furnace has all the sequencer with 6 wire connection on both sides and one of the sequencer I received has 4 wire connections
