It s a bit hard following along with all of the problems you have had… but that appears to be a picture of a pretty standard Klixon phenolic motor protector that is typically found inside a thermally protected motor. BRJ30DB = 1-1/4” diameter round base with solder connectors and will trip @120°C +/- 5°C (the “30” is the heater size, and is based on motor current rating). It should not be that hard to find a replacement (you could start by contacting Sensata at the link above to see if they sell directly or will give you a list of distributors).

However – your starter also appears to have thermal overload protection, based on the picture of it and the wiring diagram you showed a few posts ago. If so, then you only need one or the other, not both. If the starter has the correct heater for the motor, then you can bypass the klixon in the motor. If not, then you could try to find the proper heater – or you can replace the Klixon in the motor and bypass the heater in your starter (just jumper it with a piece of wire).

Thanks for the reply. I used the link you posted, the company in the link above (confirmed- the company doesn’t sell directly, at least not in this situation) referred me to a few of their distributors. I emailed them, I am waiting for the replies.

“It should not be that hard to find a replacement” I agree it shouldn’t be (but it is).

I attached a jumper a couple of weeks ago, I am looking at this as a temporary fix.

I hesitate in relying on the starter solely for regulating the motor, especially since the Starter didn’t throw itself into reset when this current Capacitor & Switch issue happened.

Thanks again.
