Hi,
I have an older (10Y) Amanc cooktop, Model AKE 35. After about 9 Years, the temperature controls started to get flakey. One would have to jiggle to keep the burner hot and rotate the control carefully to keep the connection made. First one, then another. I bought 4 new control switches and installed them. They lasted about six monthe before they became flaky too. I bought 4 more from another parts vendor and they lasted six months. I bought 4 more from Amana (pricy) and they looked and were marked exactly the same as all the others I had bought. They too became intermittant after about six months.
All these controls only have a 90 day warranty but still, one should be able to expect years of service from such controls. Maytag tells me to go scratch and just buy four more. I think I will not just send off another $90 without trying to find out what the problem might be. After each replacement the cook top works perfectly so I am sure there is no problem with the installation. I suspect a new supplier has been making these controls for a coule of years and hasen't got it right yet. Can everyone who replaces these controls be having such short life? We are a two person family and are not heavy users of this cooktop.
I hate to throw away a fine cookstove because I cant find a reliable switch. Thanks for any advice suggestions etc.
