Pry the bottom off the QP2-4R7. You may break the tabs on the bottom plate, but that's OK since we don't need the housing. Look inside and you'll see the disc held in by a short metal brace. Use pliers to remove the brace and remove the disc.
-
Repeat the process for the BQP2-4.7, but be careful not to damage the housing if you can.

-
Notice the burnt out component in the red box vs. the shiny new one in the green box.
-
Clean the leads on the BQP2-4.7 of any residue to ensure a good connection to the new thermistor disc.
-
Reassemble the BQP2-4.7 by first inserting the leads, then pushing the disc between the connectors, and finally snapping the cover plate back on.
-
If you have an ohmmeter, check that you read about 4.7 ohms across the leads at room temperature.

Good instructions; I tried doing this and was helpful. I found the actual part; it’s now available on amazon. [|Check here:] https://www.amazon.com/gp/offer-listing/...
Thanks! I’m glad this has helped some folks and I’m glad you got the part. I just checked that link and they’re no longer available. When I found them, they were five times as expensive as the other relay, but in the end the money might be worth it. I happened to have the other part, so thought I’d try the rebuild.
How long should a working disk take before it clicks off? Mine seems to get too hot after 10-20 seconds, but I see nothing obviously burnt.
Hi - it should only take a few seconds. 10-20 seconds sounds like too much, like it’s not stepping down for some reason.
I have a JPQii 4.7 two pin relay and cannot find a replacement. The one I have is new but reads 0 ohms
