Unit heating or cooling? Whatch wich contactor engages when the unit goes off - that cuircit has the melfunction. More common that one of the heating tens goes short to ground.

Yeah, what Moggy said.

Fitted second replacement OGF (on same unit) to a Vector late last year.

i have the same problem with a Vector, i searched all the electrical circuits that OGF module controls and i didn't found any leakage.Also checked the overload factor at the start up and it was also inside the limits, but the unit shuts down after 3-4 minutes of operation.Any ideas exept replace the OGF mudule?
