Hey all,
Had a MASSIVE power surge last weekend that smoked the control board on my stove - it's one of the older advantage series stove with the knobs, not the touch pad. The lineman I talked to said we all took closer to 200VAC rather than 120. No wonder! I noticed the fuse on the board was blown so I replaced it with the same type and rating (6A fast acting). New fuse popped immediately. Pulled the board out and saw that the varistor on the input is SMOKED. At first I thought it was a thermistor and after some reading on here I know what it is and what it's for. Tested it with my meter last night and it's pretty much dead shorted.
The stove was on a cheap "surge suppressor" power strip and that thing's going in the trash - I ordered a tripp lite isobar for the stove once I get it back up and running. Will also be installing an Eaton whole house suppressor in the main panel for any future spikes.
I've got a new/used board on the way which should be here tomorrow, but I'd like to get the old one up and going to have a backup as well. Would it be unwise to remove the varistor from the board and try it out to see if it still works?
I did try email Dave at pcbboardrepair and was met with a flurry of insults and expletives - not sure why anybody in their right mind would want to deal with that guy!
Thanks all.
