Can I repair the DMC1 [DMC1H] ?
The DMC1H is technically the metal box in the wall - that cannot be returned. The transformer part number is TE5D - you'll have to pull it out of the housing to send it, but we cannot authorize this return unless there have been tests done to confirm the fault.
Please perform the following based on these notes from the M&S troubleshooting guide:
If there is “No Power” on the unit—it will not power up:
· Check that the circuit breaker at the electrical box is on.
· Check that the TE-5 transformer is connected correctly. (Brown to Yellow 16-18 VAC, Blue to Red 16-18 VAC)
· Check the fuses on the back of the master unit. Replace if necessary (Radio Shack Part #270-1065).
· Reset master unit by inserting a paperclip in the reset hole, which is located behind the door.
