Thank you for your video. My cooling system kept running when the setting and inside temperatures are the same, would it be a Sequencer problem?

Zack thanks for explaining, love to learn things I don't see .

Nice Natative Zack and good job troubleshooting it's nice to hear someone speak and troubleshoot the right steps in video...
And a contractor is a relay basically just bigger and handles more load... Lol

Gentlemen, I have a Intertherm Electric furnace in my mobile home. Have been here since October and furnace will run for a couple days then turn off. Then turn it's self back on. Any suggestions for a old poor woman in Rochester N.Y. area

Will throwing the breaker for 15-minutes or so reset the sequencer?

Nic job brother. I learn something new every time I watch a vid or on the job. Good ideal on removing the high voltage wire for fan. Thanks

What does h1 and h2 mean on a sequencer. Old Lennox unit.

[gloryland]

Can I just simply check the voltage across the terminals on the sequencer itself while on the unit?

Recently replace the sequencer, limit switch, relay and the transformer due to the sequencer sticking and frying all the components and wiring. I replaced all the components and all the burnt wiring...it ran just fine for a couple months and just the other day the same issue of heat won't turn off came back..I opened everything up and found the wire from one of the heating elements to the limit switch was melted and one wire from the other heating element to the sequencer was melted....what could this be?
