Hi Robert,
Yes Please can you send me the number again. What could be taking the sequencer out. It is only about a month old.

Here are the test results from the sequencer.
With call for heat, fan set to auto:
H1/H2 24vac
H3/H4 24 vac
M1/M2 240vac
M2/M3 0vac

Hope this helps
Don

Hi Robert,
Can you let me know how to test sequencer and blower relay now. The T-Stat tested fine. Fan will not run when in auto except for after the call for heat. It seems to run on cool down

Hi Robert, I found a Yellow wire that goes from the transformer to the circuit breaker that was not hooked up. Now the fan will run in the "on" position but not in the "auto" Position. Sequencer is only 1 month old. If fan comes on and runs, that must mean the relay is good too? ...

Thanks, Tested the thermo and it seems to be fine. The blower now operates when it feels like it. Sometimes runs and other times it doesn't. Could it be the fan switch?

Thanks Robert,
Is there a way I can test the thermostat? I will check for loose wires

Hi I have a EB17B and just replaced the sequencer a few weeks ago. At that time the fan would not turn off. Now there are times it wont come on on either auto or the on position of thermostat. After some time being off, it will start to work again. Not sure what part needs replaced.

thanks
