Folks,
The power relay on the control board in my brother's GE microwave has a badly burned contact.
This is a YOUNG REEM (Korea) relay, type CS-1PD.
My Googling has not turned up a supplier for this product. The company's Web site makes me think that they supply products only to the bigger manufacturing companies. Sent them an email inquiring about the availability of a replacement. Have not heard back yet.
Do any of you know where to obtain one of these relays?
You don't need an exact replacement, just find something that will work, if the pins don't line up, jumper it in with wires. Usually the coil voltage and contact ratings are printed on the relay, find something with the same coil voltage and equal or higher amp rating on the contacts and it will do the job. Any junk microwave of similar wattage will likely have a suitable part.
Any idea why the contacts are bad, there may be a short of some type on whatever the relay controls. I would double-check that there is not a problem like this before replacing the relay. Use a jumper cable / clip lead to substitute for the contacts to make sure nothing else is bad.

Sounds reasonable. Try the clip lead and see if everything seems ok, then find any 12V or 24 V or 120V or whatever the relay requires, check to see if it is an AC or DC relay.

It is available from Samsung or any Samsung parts distributor: Samsung pt# A3068-0080 RELAY CS-1PD DC12V16A $13.46
You cannot simply substitute any old relay as it is a safety critical part if you do not want to assume all liability for the safety of the microwave after the repair.
To meet UL requirements the relay must have a specific make and breaking capacity, contact gap, and isolation characteristics, in addition to the typical electrical parameters, 12VDC coil, 16A contacts.
If you could find a complete data-sheet for that relay, then you could cross it. Given the cost of less than $15.00, I would say why bother trying to take the time to find a suitable sub.
Thank you very much for the relay's source. Promptly ordered a replacement from SamsungParts.com immediately upon reading your post.
Yes, good observation.
Moderately severe, yes. It is an inductive load, and you can compute the amps from the wattage of the oven and the power requirements from the specification plate. I'd get a relay that can handle 15 or 20 amps myself, but your choice is up to you.
