Question about Hotpoint RVM1425 Microwave Oven

1 Answer

Hotpoint RVM1425 I heated a muscle relief heat pack in the microwave. I think it's filled with sand?? After that the microwave wouldn't heat anything. I still have power and the glass plate still rotates. When I try and select a power level I get the message..power level may not be changed at this time. Also, the small fan that automatically activates when using tha microwave sounds different..a deeper roar/sound?? Any help would be greatly appreciated!! Thanks, Mark

Re: hotpoint RVM1425

The first thing I would suggest is to turn off the breaker or unplug it from the wall for a few minutes to "reset" it, then try again. If a reset doesn't fix it, I would think you may have a defective magnetron. When you heat something of very low moisture content, it can lead to microwave energy not being fully absorbed, but instead being reflected back to the magnetron. This can damage it. This is usually best left to a pro to repair. In case it might help, your owner's manual can be found online at:

Our microwave is not heating. When you turn it on it appears to be working, the dish rotates, the light is on, you can hear it running, it's just not heating the food. Is this repairable?

It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

Microwave oven will not heat? Could it be a fuse. The fan makes a louder noise than before it stopped heating. One side blows hot air the other side blows cold. Not sure what to do

Wont heat, burning rubber smell, hotpoint microwave

If there is spark please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is leaking and sparking to the ground. It is quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron.
So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off.
Now keeping clear switch on , use a cup of water inside to test.
If you notice any buring smell shut off as the magnetron or the main HT capacitor can be faulty. replace with same type.
If there is no heating the magnetron/capacitor/temperature cut off is faulty

Acceptable distance from cook top surface to microwave?

Sorry but your subject line got cut off. I'll assume you're talking about the distance from the cooktop to the top of the microwave (bottom of the cabinet to which it's mounted).

Here's how the installation instructions spec it:
  • "Make sure the bottom edge of the cabinet that will be above the microwave oven is at least 66" from the floor and 30" from the cooking surface."
So it's measured from the cooktop to the top of the microwave, not the bottom edge.

And I always recommend that you use the vent fan whenever you're cooking on the stove top to keep heat, steam, and grease out of the controls and door panels.

You can also download your owner's manual form the link I posted above.

My hotpoint rvm1425 is not heating anything up

est the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.

Thediode and capacitors can br tested. The capacitor must bealloweddischarge before testing, or you risk to get electrocuted, evenifpower is off. Capacitors can get discharged by shorting theirtwocontacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.

All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, contact the seller here to purchase parts.

Will not heat product

You can but for the safety aspect I would get a qualified engineer.
If it's too expensive buy a new one, don't take the risk to save a few £/$.

Is the unit under warranty? If not, you can try to remove the cover and see if there is a blown fuse in the section that powers the Magnetron. How old is the unit? Typically, no heating of food, indicates a bad Magnetron (tube).

Good Luck,
