90 model electric unit heat up, shut down when time for fan to start. replaced fan assemblyalredy


I recently ran across this problem with an Intertherm air handler unit of a different model. The older sequencers were pressed together and after a period of years had worked themselves apart. This controls not only the fan relay but also the heat strips at the same time. The thermo disk was not operating the micro switches correctly as a result and had lodged itself between contacts keeping the fan on. The company (TOD) apparently realized this was occurring, as the new sequencers have metal saddle straps to hold the top half down onto the thermo disk correctly. I would suggest replacing the sequencer with the Exact same model as this is very important. (power off from all sources including the 24 volt first, and verify with a meter) Make a drawing of where the wires go and take a picture if necessary.

Intertherm heater


You should have 24vac at the 2 lowest terminals 1 on each side of the sequencer with a call for heat.( that is the control voltage,the terminals are usually double spade brass in color) If you have the control voltage after about 30-120 seconds the sequencer should close.The voltage reading across the sequencer should go from 230vac to 0 volts when the sequencer closes.If you have control voltage and 230vac on each side of the sequencer then the sequencer is bad.It is beast if replacing the sequencer replace by moving 1 wire at a time from the old to the new.And ALWAYS make sure power is truned off.

Intertherm to Honeywell thermostat


Typically if you have a yellow wire in the "y" terminal blue is used as common or "c". As far as your jumper from rc to rh, that will depend upon what type of heat you have. If all of your heat and cooling come from your packaged unit outside, yes you will need the jumper. If this does not work maybe you have a bad breaker or transfomer.
