What are the watts on my '89 Blue Wave II microwave?

Apparently 800 watts.

If you know DMM then only you can fix it. Check magnetron continuity and the transformer continuity. Mostly magnetron blows up. Danger microwave has 5000 volts in it Thanks Discharge capacitors

The part number is PCOVPB085MRP0 (note ohs and zeros are different) and you can get it from Encompass here.

Check and replace as needed the door switches/catches.

magnetron is leaking internally, do not use until magnetron is replaced. the mag creates interference with the control board and resets it

Possibly a keypad short or motherboard fault if it is a KitchenAid microwave. Beware if you have a KHMS155LSS model, a Keypad short can and will cause the microwave oven to start on its own. A real stunning defect.

Look at the rating sticker on the oven and use the AC power rating as your guide. The cooking power of the oven is not important, but the power it needs from the AC supply is. Voltage times current is the supply power needed (watts), and you want an oven that will draw less than the inverter's continuous rating, less any power being used by other appliances.

For instance, a microwave rated for 120 volts AC at 10 amps needs 1200 watts. Your inverter would be OK with this as long as other devices aren't using more than another 1000 watts. You can't use the inverter's peak rating. That's only for brief bursts, like when the microwave first kicks on and draws some extra current.

Any mid-power (600 watts or so) oven should be OK.

Sounds like the magnetron has failed. There are some high voltage circuits that feed the magnetron and you can potentially get hurt if you don't know what you are doing. Would recommend you have it serviced by a professional if you want it fixed, otherwise look for a new one since the cost of repair can come close to the price of a new microwave oven.

The frequency has to do directly with the the wave a microwave oven omitts. Frequency is a measure of the number of occurrences of a repeating event per unit time. Usually microwaves run at a frequency of 2.54 Ghz, a wave length of 12.34 CM.
