How do I replace a broken light switch on an old Amana 20 energy saver refrigerator?

SOURCE: Amana Mod # ABB2223DEB Refrigerator

I found this problem addressed on applianceblog.com and per they recomended part # 67006166. My repairman ordered this part and it had been superseeded by an even newer version, # 10127429. He installed that newest version in late June 2008 and it has been great ever since. So for me # 10127429 was the answer. Hope this helps

I suspect that the cycle "button" on the control panel is intermittent.  Try using a different cycle - If you always use "short wash", try the "normal" cycle.
This worked for me.  It will be too expensive to repair, so I am dishwasher shopping.

Is it possible that with the moving a cable may have been pulled. Open the cover on the compressor connections and check that all wires are fitting snug.

SOURCE: Amana energy saver not keeping fridge section cool enough. HELP!

if there is frost build up on rear wall of freezer section the unit is not going through defrost cycle which builds up frost on evaporator and restricts cold air flow to the fresh food section. one of three things are bad. defrost heater, defrost thermostat or defrost timer. if no frost on rear wall you might be low of freon.

SOURCE: Fridge not getting cold enough

The cold from the freezer is piped up to the refrigerator and if that tube gets clogged with frost or ice it will not be able to blow to the cold air into the refrigerator area. I took everything out, unpluged the unit for about 6 hours, till all the frost from the freezer was gone, wiped up all moisture and turn it back on. It worked!
