PTC starter substitute for 8EA4B3
 

I need your help.

The PTC starter in my Kenmore refrigerator, model 795.75196400 just died. A replacement from Sears are no longer available. The part is a three terminal part labeled 8EA4B3. Only two of the terminals are connected. The third is unused. According to http://rc.danfoss.com/TechnicalInfo/...4_ct31c102.pdf 8EA14C3 is a replacement. AppliancePartsPros indicates that the PTC starter LG 6748JA3001A (part AP4857702) would work for my refrigerator, and also refrigerators LG LRTB2023BS and LG LRTPC1831T. Repair Clinc confirms but AP4857702 is also unavailable.

Parts Store indicates that 6748C0004D is a substitute for 6748JA3001A which would mean that it should work for the cited LG refrigerators. This part is widely available. However I cannot find anyone saying that 6748C0004D is compatible with Kenmore 795.75196400, so I am not sure.

The main board has a 12uF, which I assume is a run capacitor. According to http://forum.appliancepartspros.com/...tml#post271274 the broken part can be replaced with GE WR07X10051.

From what I can tell any of the following would work:

• GE WR07X10051
• LG 6748C0004D (aka AP4439465)
• AP4857702 (not unavailable)
• any others?

It seems like there are lots of different mfg part numbers that use similar (if not identical) PTC starter relays. But I'm not sure.

Any ideas on which available PTC starters are compatible with a kenmore is with an EGZ 80HLP compressor?

Thank you.

Did you note which fridg wires went to which ptc device terminal? If so, I would use the GE ptc device, cheaper and much more reliable, just wire it up per the old one.

I noted the original wiring when I removed the original 8EA4B3 PTC. As you suggested I reused the same wiring pattern with the new GE WR07X10051 PTC. I installed it and it is working great. Thanks for the help!

For reference I noted the wiring pattern. When mounted on the compressor and looking at the PTC relay, pin 3 is on the bottom right and connected to an orange wire; pin 2 is in the bottom left connected to a blue wire.

Very good work, as I said before, you must wire it up the same as the old device or you will burn out the start winding. Thousands of customers use this ptc device when it is listed as a direct replacement with no problem as long as they wire it the same as the old one.
