Tekmar 371

My tekmar 371 died. We had several power outages. I have checked the fuse on the circuit board and it is good. Any Suggestions?

Yes the power is on.0 -
Put your nose right next to the control.....
and take a whiff. Does it smell of acrid smoke? If yes, it's fried.
Solid state electronics do not like surges, man made or otherwise. I've seen holes the size of a silver dollar burnt through boards on tekmar before.
Sorry I don't have better news for you. There are no internal fuses or circuit breakers.

Surges, fuses, and solid state electronics.
When I used to design electronic equipment, we had a saying: the transistor acts to protect the fuse. This was because a transistor can be fried by a one microsecond surge, while a fuse tends to take much much longer to blow. A fuse can perhaps protect against long-term overloads, and is a good safety measure for a system to protect the building it is in, but it will almost never protect the electronic equipment itself. For that you need good wiring and a suitable surge protector.0
