Of course I am aware that the interlock would not be interrupting the 3KV but it does form an input for your control board. 3KV is about the minimum operating voltage for a magnetron. Perhaps your well-aged magnetron is no longer reliably operating at 3KV. Before you invest in a replacement part, price out a new oven. We recently bought new appliances for a kitchen remodel and the very nice new microwave oven was the least expensive item and has a host of features that are likely absent from your old unit. Also much lighter and easy to install. |

Sad as that may be when one likes to fix things! Mind you I collect old battery radios from the 1920s - and a modern radio doing the same thing might cost all of $10.

Amen to the joys of tinkering. I used to think that opening a tinker shop would be fun, but the reality of the throw away society put a stop to that. I know that there are some makerspaces (maybe also schools and libraries) that have fixit events, where you bring your busted toaster or whatever and it becomes a group project to fix them up. I do like that concept. I am currently awaiting delivery (today) of a replacement magnetron. Hopefully I'll have results before the day is done. |

We recently bought new appliances for a kitchen remodel and the very nice new microwave oven was the least expensive item and has a host of features that are likely absent from your old unit. Also much lighter and easy to install. New magnetron should be here today - for better or worse, at least there will be a definitive answer. I really don't want to buy a new microwave. Yes, they are not *that* expensive, but they *are* several times the cost of a magnetron. Also, hanging this thing back on the wall is literally a one-minute project. If it takes any longer, that means something has gone terribly wrong. A new oven would mean a new mounting plate and at best, that's way more work. |
