replacement relay for refrigerator motherboard

[tortillasoup]

I have a subzero 650 refrigerator and I need to replace the relays on the motherboard. Apparently the relays on this board are prone to failure in the closed position which causes the compressor not to shut off. The refrigerator was built in the year 2000 so that may explain why a 16a version of this relay is no longer made as it was obviously prone to failure when used above 10a.

This is the model number of the relay that failed:
NAIS/Panasonic/Aeromat relay model JW2H-T-F-DC24V-Y8-H
says 24VDC, 16A/240VAC on the top of it

here is the incomplete datasheet:

(It looks like their relay has been downgraded to a 10a from a 16a they used to sell probably due to this reason of failing in the switched on position)



This is another relay I may need replaced:
oje-ss-124lmh says 8a 240VAC, 8A 250V, 24V (switching current?)

datasheet:

I can provide pictures if needed.





Update:
On my Sub-Zero 4202800 Control board, instead of spending $250+ to purchase a new motherboard, I had the Omron G2RL-1-E-DC24 relays soldered onto the motherboard to replace the existing defective relays.

The relays are the same ones used in the later revision of this motherboard and thus far, they appear to be working properly.

I moved this thread because it has nothing to do with computer hardware.

Try digikey http://www.digikey.com/en

Coil switch voltage is the important part, you want to match it, the amps just need to be same or higher, given it failed perhaps I'd go higher, the inrush current of the compressor is probably what did it in, so you probably want to oversize. Too bad it's 24v and not 12v. With 12v you could probably use an automotive relay.

But yeah I'd check digikey, you can sort by various parameters.

You may also be able to source one out from a local electrical store that sells industrial process stuff.

Yea lol was just going to post the same... Searched part number

I will add this http://www.saferproducts.gov/ViewIncident/1227605

Are all of the pins of the relay socket going directly to the board, or are there spade connections coming off of it?

If the latter, and there is space, you could just take the 24VDC trigger from the board and run it to a contactor. Then run your line/load to this contactor. Allen-Bradley makes some of the best in the business, IMO. This will be an expensive and bulky solution, so I would definitely try to source the OEM part first, but it could stand to be more reliable, too.

that's the old one though. That one is prone to failure and was apparently de-rated as they no longer offer it in anything above 10a.

Anyway I think I found a suitable replacement:

Unless someone can explain if this isn't a sufficient replacement.


Oh and all the pins go into the board.

Looks like you found a good part, unless you want to get the old one 6 months from now at oldsmoboat's link.

My solution would have been hack, and physically impossibly since all pins go into the board.

That 16A is line voltage I am assuming? No wonder they fail, passing almost 2000 watts through a coil and printed circuit board is a good way to insure failure if components are not specced right.

It's a smaller compressor since these units have two of them and it's the larger of the compressors. It really shouldn't have failed but when you consider that the initial loading + the fact that the relay was rated higher than what it really is good for, it's not a surprise that it failed in the closed position after 15 years.
