Hotpoint Over the Range Microwave is LOUD

It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.

YOUR SAFETY IS PARAMOUNT

This is a job for a professional but if you are safety clued up, here's instruction.
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 or moving coil meter on high resistance range for short circuit, (DVM's won't show the fault!), the capacitor can fail and go 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.

Load test.

A simple safety test.
Place 1/2 litre of water in a glass container. Measure the temperature of the water.
Place in microwave and heat on full power for 1minute.
Measure the temperature after it has stood for 1minute.
If the temperature difference is more than 9 degrees Celcuis the magnetron is working and producing about 700Watts of heat.
If your microwave is labelled with 900 or 1000Watts. That is about right.
If the temperature is less then the magnetron is not working properly and may need replacing.

This a only a rough guide and any doubts you should consult an authorised service agent.

What usually happens to make the plate break or shatter is heat build up in one place, caused by spillage of food stuffs that have "welded" themselves to the plate or a scratch on the plate allowing water to enter and when it gets hot explodes the plate.
There, from what you have explained and the information you have supplied, no reason to doubt the machine. A new plate and it should work again with no problem.
Hope that puts your mind at rest.

It is much easier for two people to remove the microhood. If attempting alone, please move the range out so you can get under the micro to support the weight. If the range stays in place, protect the top from damage.
1. make a landing site to the side to protect the floor when putting the micro down after removal.
2. Disconnect the power cord in the cabinet above.
3. loosen the two screws in the bottom front corners of the cabinet above. When removed the front of the micro will drop, be ready for the weight. Busy times, tools in hands microwave coming down in front.
4. tilt the front down. pull the cord out of the upper cabinet.
5. with micro still tilted down in front, lift the back of the unit upward to free it from the wall plate.
6. remove the fasteners in the wall plate and remove.
Congrats, begin celebration.

I have had all the same problems as you! I fixed it myself for less than $3. Go to home depot buy a CERAMIC fuse for microwaves its in a yellow and black package, take off the back of your microwave and replace the fuse! anyone who tells you that you cant use a ceramic fuse is full of themselves so dont listen to them.

When a fuse even starts to go bad, even though it looks intact: it can make your appliances do strange things. I changed the junk glass fuse with a ceramic one and the microwave worked like it was new out of the box. Give it a try, dont scrap your microwave.

If the unit is brand new as you say then it is covered under the warranty and the 800# for Bosch is in your paperwork that came with it.

It sounds like the glass platen (turntable) hub is either binding or else the drive mechanism itself either has a bad tooth on the main gear or tooth wheel. Some may still use a chain type drive mechanism as well.

If you call that 800 number - the customer service dept there will advise you as to what needs to happen next. It's possible they will either replace or repair at their expense.

Who installed the unit?

Let me know?

Best regards,

Frank

Either the coupler or the turntable support is bad.

You can find an exploded view by entering your FULL model number (3 digits, a dot, then 8 digits) here: http://www3.sears.com (the 3 is correct)

Could you describe the noise?

It may be a noisy fan motor or a failing magnetron or high-voltage transformer.

sounds Like an electrical fault in the Micro, Sorry but this is broken.... If this is within warranty (do check as some warrantys are for 3 yrs or more) get the manufacturer to replace/repair it for free. you could get it serviced, but it is probably cheaper to buy a new one.
