Re: Whirlpool gas oven ps/control board burnt resistor

I will not be using the old switch, just not worth the chance of actually killing the board. I have checked all the wiring. I feel like the carbon track is the most viable explanation and that it was arcing on the metal clip which is chassis ground. I guess, sort of tracing the whole board out that the increased load drew too much for the resistor on the ac side.

Re: Whirlpool gas oven ps/control board burnt resistor



Thank you

I see no crack but the carbon track could be it, who knows it is the most actuated switch in the system. My dad was never behind the stove when trying it so he could not see it but it lit up pretty good.

I'm just glad I got it fixed and saved them $250, the switch is an expensive little bugger at $50-$70. I may try to find some other switch though. This one takes a rod from the front to the switch, kind of dumb if you ask me but maybe it gets to hot right under where you...

Re: Whirlpool gas oven ps/control board burnt resistor

We need not speculate any further and I APPRECIATE everyones contributions!!!!

Ultimately the procedure was similar to what we all have discussed in the last few posts. I plugged in the board with a hot and neutral in the stove. All the connectors are spades in molded plastic so I hooked up the dc side plug only and began testing voltages out as my brother picked bake, broil, etc. The light showed hot no matter what but only like 70vac, so I proceeded to desolder the K1 relay. We tested it with a 9v battery...

Re: Whirlpool gas oven ps/control board burnt resistor



That was my thought if nothing jumped out at me when others had a chance to examine my work so far. I did double post but only had one reply that said it may be a waste of time and to contact a pro. I want to learn so this is only a waste of time once I stop learning.

I am busier then I expected this weekend but figure tomorrow I am going to go to my dad's and test all the stove components and if they test good then do as you said and start with just line and neutral and see when the resistor pops...

I test it with ac connected to L1 spade and Neutral spade U13 is the Viper12a...

Re: Whirlpool gas oven ps/control board burnt resistor



One relay actuated (sound) when plugged in on the bench I will have to trace it and see what I see.

The way my dad tells it is he hooks everything up then plugs in the power cord. It comes on for a second and burns the resistor. I checked some of the components with his crappy meter but will have to take my better meter over and verify no ground on light and door circuit.

This is the only board that deals with 120v the other board should not come into play until the buttons are pushed...

Re: Whirlpool gas oven ps/control board burnt resistor



Okay I can remove the relays and check them. They are all one legged on the hot trace, I did not consider that. I will try to test them tonight and report back.

I can still check But according to the connection figure for three of the four relays on digikey there is no back-emf diode: [URL="https://www.digikey.com/product-detail/en/te-connectivity-potter-&-brumfield/T77V1D10-12/T77V1D10-12-ND/1427693?&gclid=CjwKCAjwtajrBRBVEiwA8w2Q8BhUCdpeIWTpxOgB_pCH9jPRn-UunjQC37OaQAhUp_by-dTlMrcBVBoCd9kQAvD_BwE"]https://www.digikey.com/product-detail/en/te-connectivity-potter-&-brumfield/T77V1D10-12/T77V1D10-12-ND/1427693?&gclid=CjwKCAjwtajrBRBVEiwA8w2Q8BhUCdpeIWTpxOgB_pCH9jPRn-UunjQC37OaQAhUp_by-dTlMrcBVBoCd9kQAvD_BwE[/URL]...

Re: Whirlpool gas oven ps/control board burnt resistor



Just a mounting hole for a screw if that option was used here, it is not, and it has some coating that ran over on it. Looks funky in the pic but just verified physically on the board....

Re: Whirlpool gas oven ps/control board burnt resistor

Thank you petejall347. Should be easier that way too.

Hello all,

I am attempting to repair a control board for a gas oven. The initial fault occurred after a lightning storm, the digital read out and all oven controls ceased to work. Upon inspection I found a resistor on the line side to be open. I replaced it with a 1/4watt as that is all I had at the time. I applied power to the board while on the bench and it worked (display lit and buttons functioned), however when my dad plugged it all back in it "sparked, crackled and shut off". I then purchased .5watt resistors and we tried again. Again it burned out the resistor. I...

Re: New Members - please post your introductions here

Hello all my name is Robert I enjoy repairing equipment both mechanical and electrical, I have always had a desire to repair and understand electronics and have acquired a fair amount of knowledge about components over the years. Now I am trying to learn more about building circuits and repairing them.

I am working on repairing a control board for my Mom's oven and would like some assistance so I came here to see what I might learn, as I love learning!
