I havea hot point mode RVM1635 that lost total power not surewhy

sounds like the control board, but most times the magnetron fails and if a fuse failed then it needs a capacitor too

Might be a fuse inside, or the unit may have died. Contact the manufacturer and keep the unit unplugged.

The magnetron is the other issue, high voltage diode will sometimes crack causing a high level short, the capacitor developes a dead short across the 2 points, the power transformer almost never fails, "very rare"

Your RVM1435 microwave is rated at 950 Watts for cooking. Total watts will be slightly higher as the power used for the display, clock, etc. are not counted for cook power. Here are the rest of the common specifications.

I hope this helps - please rate my reply. Thanks.

Dead appliance, power on wall outlet.

YOUR SAFETY IS PARAMOUNT!

Attempt this only if you are competent.

If your appliance has absolutely no functions at all, remove it from the mains supply, remove the case and see where the mains lead goes in to the appliance and follow the cable until you find the main fuse.
ONLY USE THE SAME TYPE AND RATING OF FUSE TO REPLACE IT.
The usual cause of this fuse failure is the door switches are contaminated or sticking. Check the door switches before putting power back on to the appliance.
Hope this helps.

Press "Power" until you get to the level you want. Then enter the # of minutes on the keypad (CANNOT use express cook times.) An alternating runnig hum will let you know the setting is working.

Open the Micro door, and remove the air/Vent cover on the top if there is one, Usualy 2 screws on top or the middle of the cover.
Remove the screw holding the Controller board and then you will have access to the door switches 2-3 of them depending on Manif.

Also make sure you have the power unpluged befoe you do any of this.

Good luck!

The first thing to try is a "hard reset". Unplug it from the power line for a minute, plug it back in, set the clock, then try again.

In this case, they have the RVM1625, and it may be close enough.
