I currently have an electric furnace and, with the thermostat off, the sequencer is turning the heat elements on. Thermostat off. Unit keeps heating. Fan off. Just random turning on and off of heat elements, this issue started after I put everything back together after a deep clean. So the sequencers are working, but im not asking for heat. Any ideas?
@ntexashvac72403 ай бұрын
So what’s happened most likely is the ceramic rod that holds up the contact inside the sequencer has broken. When that happens the sequencer actually fails in the on position so it’s actually not working properly because it’s heating without a call for heat. The intermittent on off comes from the high limit switch interrupting the electric flow and heating as the temp inside the heat kit rises due to no airflow because the fan is off. You’ll need a new sequencer.

If you have the heat strips running at the same time as the A/C, what would be the symptoms? Would you have super high pressure readings on both the high and low sides, making it appear overcharged? And would your delta T indoors be cool but lower than normal?
@ntexashvac72409 ай бұрын
Usually In a conventional air handler the heat strips are down stream of the coil so as far as your pressures are concerned they will look to be normal. The delta -T will be low because the cooled air will be heated downstream by the electric heat. The fastest way to diagnose a stuck on heat strip in the cooling months is to amp clamp the line voltage at the air handler while your set to cool. The blower only pulls a few amps so if your getting amp readings like 15amps and higher then you have a strip on. Each strip typically pulls about 20amps but some are a bit lower. But no blower is pulling 15+ amps under normal operation.

Thank you for the helpful videos. I've run into an issue with my electric furnace that happens atleast once ever couple of days: The thermostat will call for heat, but the furnace never comes on. While testing, the only way i've gotten it to work again is jumping the fan wires (R & G) for a second or two. 5 seconds after I do that, the furnace will kick on again and go off at the specified temperature. Do you know what could be causing this and how to troubleshoot? Last time this happened, jumping R and W did not work.
