    Muskoka SF310C-36 electric wallmount fireplace will not turn on.

    73's de Edd: Further clarification of the traces around the ULN2003A and the four resistors R19, R20, R21, and R22 which are somewhat unclear in my first post. The right most resistor R22 is continuous with pin 4 of the ULN2003A IC4 and follows the trace under the Darlington Array to pin 7 of...

    Muskoka SF310C-36 electric wallmount fireplace will not turn on.

    73's de Edd: That was a very impressive analysis of the control board. Also very good eyes to notice what could have been a crack in the copper side of the board. That was my bad as it actually was a fabric strand off a sweater. So crisis averted there. Your analysis of the 3 relays was...

    Martin, some further information. connector CN1 on the component side of the board connects to push button board on the side of the fireplace. Connector CN1 shows 5VDC and GND when 120VAC is applied across the ACL and ACN pins. CN2 also shows 5VDC and GND and it is connected to the IR...

    Hi Martin, thanks for the reply. Fuse F1 is continuous when I check it on the board and off the board. So I assume it is not blown. The diodes D1-D4, I assume are a bridge rectifier for AC to DC conversion. All 4 show OL in one direction and 0.594 V in the other when I check with my...

    The above fireplace will not power on. Three relays are on the control board to control the 120VDC but the control VDC seems to be missing and I have not been able to find where it is supplied from. Pictures of the control board front and back are attached.
