Microwave ???

[ilvtravln]

There is a clock on the microwave, if its on microwave works, if not it doesn't, clock has been going off and on all by itself, breaker never trips, Any idea why the microwave keeps loosing power ? Brand is Apollo, its 17 years old. Thanks

My guess is it would be a loose wire or bad contact. At that age, it might be time to look at a new microwave. When the then 19 year old Sharp MW in our rig got flaky, the replacement cost at Camping World was $365. Instead, I took the dimensions and a tape measure to Walmart and found an exact fit except an inch shorter depth from Hamilton Beach on sale for $88. Some minor bending of the vented surround mounting straps too care of the depth difference. Oh, and some small wood shims to adjust the height so the mounting holes matched the existing screw holes.

Low or intermittent AC voltage? Do you have shore power or are you running the MW on an inverter?

Shore power, at an RV park now, everything else works perfectly.

Thanks for your reply, at 17 years old I was figuring its about time for a new one.

Have you performed routine electrical maintenance? Open up the power center and with generator off, and shore power removed, tighten all connections, The ground bar, the neutral bar and the screws on the breakers. Also the 12v connections should be checked (but they are not related to this problem, I'm suggesting it as routine maintenance.) Is there a built in electrical management system? If so, it also has connections that need to be checked. In addition, you should probably remove the MW and plug it into a different source and see what it does. There are many things that could cause this and the last thing I would be doing is replacing a MW before eliminating all of the electrical system leading up to it. Too many things in an RV to go bad or wrong to assume its the MW.

Before condemning the microwave get an extension cord and plug it in to a different circuit. Then you'll know if its the MW or the circuit without guessing.

True story.. I should know.. Read on.
When I got my Class A the microwave worked fine but the Air condtitioners.
Sometimes the front on worked. Sometimes the rear both or neither and It was annoying.

Well so are trips to the dealer and electrical'/electric are in my juristiction so I got out ye old Multi-Meter and a flashlight and opened the master breaker panel to start seeing looking for where BRIGHT on a test light turns to Dark (only at 120 I had a meter not a test light).

Hit one of the wire/breaker joints with the meter probe and ... the wire moved. YES MOVED and I'm either sitting or lying there on teh floor (The breaker box was avery low level like 2" above the floor so if I'm lyng down eye level) and got up and grabbed my #2 Square drive. One screw took 3 1/2 FULL turns... I then when on to tighten every screw in the screwy box.. Never had that problem again bvecause as Rachel the RV Girl (Well that's the license plate on her mobile RV service van) Says "When I( tighten them they don't come loose" (She And I both).

Given your symptoms are identical... Suggest you start with the breaker box Make sure all tight. all 3 colors.
