Doing some 120V electrical work, turned off power to boiler room. On restart no display and blower runs constantly. Have 120V power to switch and to control mod. Is there a fuse? Where is it located? Any other ideas of what may be wrong? Thanks for any & all help

    Fuses

    Yes, under the cover. Check your polarity, also.

    I looked under the cover and did not see any fuses. I also did not find them showen in the wiring digram. Location? front, back or in very rear near wiring strip? Polarity is OK. Very odd problem as it was working prior and the electrical work did not involve the boiler

    They are listed as

    Control Module fuses I would check control module and wires to and fro. Two are listed though not shown in the book if not found call 219-879-6561 ask for Technical Services.

    So who messed up?

    You stated that the power to the boiler room had been turned off for other work. The boiler should be on a dedicated circuit, did someone screw up?
