	Looking for wiring info on Kenmore Model 1O657287790 Refrig. Does the evap fan cycle with the compressor? It seems like the whole thing is dead until you touch anywhere in the control panel area, then it comes on and may work right for several days. I replaced the defrost timer and it worked for about a week and is down again. On the equipment I am familiar with, the evap fan runs all the time except in defrost. Trying to determine if it is a thermostat failure or a bad wire in the harness. Since it starts running as soon as you touch it, then won't fail, I cant catch in failure to check. I have searched for a diagram but not been able to find one. -- JHF __________________ If it's too good to be true, it probably isn't

	The model number seems to be incorrect....it could be the defrost termination switch....You may not be qualified to repair this unit... http://www.searspartsdirect.com/partsdirect/part-model/657?page=1 __________________ All living things seek to control their own destiny....this is the purpose of life

	How would the defrost termination (misnomer) enter into the cycle in the cooling mode? That is why I am asking if anyone has a wiring diagram for this old unit. The number was good enough for the parts tore to get a defrost timer. -- JHF __________________ If it's too good to be true, it probably isn't

	On some refrigerators the defrost cycle is terminated by a thermostat attached to the evaporator coil, the defrost timer is stopped until this thermostat reaches temperature and makes the switch....I get "no match" when I punch in your supplied model number at the Kenmore parts link in previous post....If I had a schematic of this unit, I could be more specific... __________________ All living things seek to control their own destiny....this is the purpose of life

	Any time you move a device and it starts running then it's usually a bad connection of some type. Check all the wires in the control panel and make sure the terminated ends are fast. If so then move the harness around to see if you can get it to cause the failure. And just because the movement of the harness cause a failure do not take that as a bad harness. The wires in the harness may be moving the wires at the devices they are connected to just enough that the loose connection is at one of those. __________________ Life is not a journey to the grave with the intention of arriving in a pretty, pristine body but rather to come sliding in sideways, all used up and exclaiming, "Wow, what a ride!"

	There are mechanical relays soldered into a vertically oriented PCB. The lead free solder does not hold up to vibration well. cycling of the relays actually fractures the solder joints and causes intermittent failures. I've seen this in wiper delay circuits, valve controllers, and appliances. The fix: Remove conformal coating, resolder everything, recoat with clear spray paint __________________ MikeMack747

	I think the second digit in model No.should be a (zero) 0 not the letter O .....you get a hit from that.....just a guess.

	Go to the SEARS PARTS web site. They have schematics of most of there appliances there. Also look within the compressor compartment. It should have a wiring diagram there or on the panel. If you still have the owners manual there may be a print in there. Good Luck, Old Salt __________________ Any day on the green side of the grass is a GREAT DAY!, --- me +++++++++.
