I've had a guy out to fix my fridge a couple of times now. The initial issue was with the circuit that controlled when the defroster should turn on. After he replaced that, we had an issue a couple weeks later with the vents icing over and it not blowing cold air. After he cleared that out, it broke again a couple weeks later. This time the power switch fuse was blown. The repair guy came out with the owner of the company this time.
They didn't have a replacement switch on them, and I think didn't want to come back to see me again, so they just bypassed the switch so that the fridge power is now always on (I can still cut power at the breaker if need be, of course).
Is there any safety issue from letting it run this way for a while? Bypassing a fuse sounds like a no-no to me, but I'm just a layman and I don't know anything about refrigerators.
