Our 1980 vintage Amana radar range's timer went goofy. Touch pad generated random numbers. As you can see the time displays 3608. I figured to shotgun the power supply parts and see if that would get it going again. There is no place in town to get parts so I ordered them from Wholesale Electronics Inc out of Mitchell South Dakota. www.weisd.com. I replaced two zener diodes that regulate voltage and three electrolytic capacitors. One of the caps was not available in its original 250v rating so I substituted a 350 volt. parts cost $5.28 and shipping was $11.90
Timer out of its hole. This thing is built like a tank.
Stud mount triac came unbonded during disassembly oh well.
Two of the caps that got replaced the zeners are next to the transformer
