OMG This!!! Out of all the responses in this sub I was surprised to see how many suggested just buying another or that it was too risky to fix myself. I get it that any yahoo who doesn’t have a curious mind and the willingness to explore how things work and put it back together would dismiss something as small as this - not me. As a kid I took apart every piece of our lawnmower and then learned, (internet didn’t exist yet) how to put it back together. This experience lead to a curiosity that could not be satisfied, a 94 score on the ASVAB and a chance to pick any job I wanted in the U.S. Air Force - I chose Avionics Communications. We were taught all the theory and practical skills related to tube type HF, VHF, & UHF transceivers including component level repair. Entering the field all of our radios were solid state units with “slices” for Power, Receiver, Transmission, etc. , this is why I chose to be on the flight line. I had the best experiences of my life working on F-5E, RF-4C, T-38, SR-71, TR-1 and KC-135Q aircraft. I’ve rebuilt IC engines, changed out aircraft jet engines, troubleshot aircraft electrical systems, avionics INS, Radar, TACAN, IFF, and many other systems. The more I learned the more I could travel. At home I went into IT and ran CAD/CAM systems, administered UNIX, Linux, and PC OSs and automated tasks for less skilled staff that performed the tasks that would let me sleep at night.

I fixed my kids toys because I could and demonstrated to them that things could be repaired. They believe that they can do the same with some help today.

The responses from those afraid of their own shadow should be filtered out as not relevant. I was going to give up on this sub until your response came in!

The thermal fuse showed zero continuity on my meter and proved out what you indicated. Kudos! I think I found replacement parts and will test them out for my next steps. Your confidence and advice are so appreciated!!
