Please help with Weil McLain heii ecu unit flashing!
Thank you in advance guys for taking the time out to help me. I was affected by hurricane Sandy and my contractor who is very handy told me he can get it going by replacing some parts.
ECU- the electric control unit
The two or three other parts are working fine and were tested with a voltage meter.
So when we turn on power this is what happens:
Thermostats call for heat
Blower and circulator turn on
Power light on
Purge light on
Limit light on
Stays like this for about 5 minutes and then the power light and pressure switch flash.
The ignitor never comes on
