If the owner’s manual doesn’t say google your make, model, year and “check engine” and somebody in the interwebs will have figured it out.
Right? We have fixed our ice maker, washing machine, etc. using google. Ice maker-I actually fixed my pool pump this summer using youtube and I am the least mechanically inclined person on the planet. Well, my 13 year old helped me and he is among the pretty mechanically inclined.
We bought the icemaker part from a retired appliance salesman on Ebay who sells parts for about $15.
