Not heating

Usually one of three things and not in any order:

The diode commonly used in most microwaves= it cannot be shorted and work.

The inverter board which powers the Magnetron.

The magnetron itself which does the work and can only be tested for sure by replacing.

Sharp microwave r95stm not heating

This a common problem, the likely cause is a bad magnetron "heats food" and is the heart of the microwave oven, if the item is five years or more, cheaper to replace.

My sharp r-209hk suddenly stopped heating. the motor makes more noise and food won't heat

If there is no heat it is the Magnetron. The other 1 from the 9/10 is the HV (High Voltage) Diode that connects to the HV Capacitor.This is the cheaper fix of the two with them being usually under $12. The Magnetron is rather high ranging from approx. $50 and up.Have the blown parts replaced.Thanks

Hi, I have a SHARP Microwave Model R398F. Its less than a year old. The display and timer work fine but does not heat up. Can you please let me know what the problem could be. Thanks Js

If the operation is otherwise normal with the exception of heating food, common causes include; (to diagnose requires discharging of the HV capacitor) if you are inexperienced with working with HV I suggest seeking professional help.

Open thermal protectors or thermal fuses.

Open HV Diode.

Open HV capacitor

Open magnetron filament

Open winding in HV transformer

Defective HV relay

Shorted HV diode

Short or other fault in the magnetron

Short in certain portions of the HV wiring

Replacement Magnetrons (the most likely cause if not charring or defective components are found when troublshooting the small parts, can typically be had for around $45.00 just do a web search for your model number.

Good Luck

I have a 1993 GE spacemaker microwave/range hood combo. Everything works except that for most of the day it did not heat the food. The turntable still worked and the oven still appeared to be running. Then...

In short yes it can happen again.

Intermittent operation can be caused by a door interlock micro switch, a weak capacitor, an intermittent wiring connection from heat or poor connection, a marginally performing diode or a sticking Magnetron. Except for the Magnetron all other repairs would be worth the expense.

Repair costs and parts for most everything else will be between $65 and $100.00 depending on the part(s) replaced. Replacing the Magnetron would cost more than 50 % of the total unit replacement cost.

Sharp carousel microwave model # 508ak has power but does not heat food when you press the start button. thanks in advance!

9 times out of 10 this is usually this is a bad magnetron, the other time is sometimes a bad high voltage diode. See components section. Q - My microwave is running and sounds like it is working but will not heat up anything.
A - Many thing can do this but, common things are....loose high voltage wire.....poor solder joint on board.....magnetron.....power relay.....

Q - The microwave display counts down and the inside light is on, but nothing is heating and the fan is not running.
A - This most commonly is a bad door switch, other possible problems are a faulty relay or solder joint on the power module, but a bad door switch is most common.

Sharp microwave losing cooking power

If the supply voltage is low it will take long time to heat foods. The second reason is the Magnetron. Since it is in the warranty period you can call at the sharp authorised service center. They will do it free of coast.

Microwave turns off after 10-15 seconds.

Make sure you hear the fan is still operating in your microwave. Next is to make sure the air intake grill on your microwave is not plugged up with air borne dust and dirt.

JVM2050 Doesn't cook food sometimes

Not the magnetron if intermittent. Probably a bad smartboard. Easy to replace if you know the basic precautions to take.

No light, internal fan...then no display

The light isn't a safety issue but I would think that the fan would be.

The fan is designed to remove excess heat from unit and keep it cool. Without the fan, you're now operating the unit under conditions that it wasn't designed for.

With the unit unplugged, try removing the cover and see if a fuse has blown. If so, replace it with the EXACT value of the original.

See if the unit powers up again. Try heating heating up something for 30 seconds to see if the Magnetron is still functioning.

If so, check to see if the bulb is good. Did the bulb and fan stop at the same time? If so, it might be something in common that controls both.

Don't operate it further until you have it looked at. You don't want to cause something else to fail.

Good luck!
