I don't know about parts, I do know performance, however I think it's well worth grabbing. Someone I have known for a long time, but who is not always in my kitchen was amazed that I had my 1986 Radarange. Lawrence/Maytagbear | ||

thanks for that info Lawrence Hans & Phil!
i think I will try to snag it, a bit more research shows it's a 1974 RR-4D, the first Amana model with Defrost. Internet research shows yours might be a RR-2 Phil, even older, and has the Blue "Light" bar while RR-4's was White. This one is very nice shape and has all the books with it. Will post pics if/when I get it.
Love those d/w's Phil, 'specially the Pank one!!! sweeeet! | ||

Apparently RR-4D
Magnetron is NLA, but, like older tube audio stuff, capacitors can often (ie always eventually) go bad, and apparently is known to happen on these, if that's the problem, Sandy, it's fairly easily rectified as it's just a matter of desoldering the old one(s) and soldering in another(s). Most Illinois caps I use on old amps run 1-2$ ea. max. A schematic is helpful, if available, and if one comes with this one I can copy it.

Many repairs are simple
on these older microwaves as there weren't a lot of parts to fail. Pretty much a timer a big high voltage transformer a couple rectifier diodes a filter capacitor and the magnitron. Often the failure is just a fuse or a bad interlock switch.
Unlike electrolytic capacitors in old audio gear the oil filled high voltage capacitors in microwaves don't fail due to age. Even if exact parts aren't available I'm sure parts could be substituted, perhaps even a magnitron if you could find one with the same mounting flange. The rectifier is likely the most fragile part of these earlier ovens. If the oven has variable power then there is a Triac and its control circuitry in there too. Sandy, its fair to be hesitant to poke around in a microwave that is under power. But there is nothing dangerous inside if you let it sit unplugged for a few minutes (short the terminals on top the capacitor with a screwdriver to be sure). Look around for a fuse that is blown etc., the failure may be obvious! | ||

firedome . . . I don't need a hood off a '66 Saab 96, but I sure understand the logic behind buying a parts car because you just have to have one NLA assembly . . . I once bought an entire car just to get the headlights, LOL.

The PCBs in old oil caps
are also quite carcinogenic. Even Electrolytics can discharge enough voltage to be dangerous if fairly recently recharged by powering up the appliance, ie not sitting for a long time, and those should also be discharged as detailed above.
I'm told these old RadarRanges are quite durable and reliable, far more so than new junk, and many are still in service out there. Weight is around 90 lbs!!! | ||
