Don't heat consistantly micro or conv--sympthems-- no oven light no heat --occasionally ok--- ser. #113806


Hello there,

The problem could be from the power diode. A diode is an electronic component that readily passes current in one direction only and blocks the flow of current in the opposing direction. If your microwave's diode has become defective, your microwave will not heat and you will hear a buzzing noise. Test the diode to determine if this is the cause of your problem. Replace it if it is defective.
Also a capacitor could be faulty. A capacitor is an electrical device which stores electricity. A defective capacitor may be why your microwave is not heating or working intermittently. The capacitor will have to be tested to determine if this is the cause of your problem. A defective capacitor will have to be replaced before your microwave will work again. Make sure you discharge the capacitor before you test it, though.
Finally, the magnetron could be faulty. A defective magnetron is the third possible cause of why your microwave is not heating. Test your microwave's magnetron. Replace it if it is defective.
You will have to test them and replace the faulty component amongst the three factors.
Hope this helped.
All the best.

Sharp R-340H Microwave has power but does not heat food. Carousel working.


The magnetron is the likely problem, "heats food" the other two items to check is the high voltage capacitor and diode. It usually is cheaper to replace.

Sharp microwave r-1875. Replaced damper motor. upon start up sounded like it blew a fuse. Where is the fuse located


The fuse located under the keypad near the high voltage capacitor "silver and rectangular" unplug and discharge high voltage capacitor, fuse is a ceramic type, replace with same type and rating.

Why would the high voltage capacitor go bad?


Hi and welcome to FixYa. I am Kelly. High voltage capacitors can and do fail when a microwave is used for long periods of operation, when the unit is operated with no internal load and sometimes for no reason at all other than the capacitor had an internal failure such as corrosion or a break down of the metal strips inside of it where the strips can make contact with the the case. I have been working on microwaves since the 70's and often there is no apparent reason for the failure of the HV cap.. They just sometimes fail.
However...... there is also a power diode in the microwave that is connected directly to one terminal of the HV Cap. If the power diode has failed it can cause subsequent failure of the HV Cap. The Sharp Power diodes can be found here: http://www.repairclinic.com/Sharp-Microwave-Parts?s=t-FH-DZA119WRKZ-%3d%3db113a6c41

You use and ohm meter on resistance to check the diode AFTER removing the terminal of the diode from the capacitor. NOTE: the capacitor must be shorted across the terminals at least 3 times with a screwdriver while holding the handle only to prevent a horrible shock.
Once the diode terminal is disconnected from the HV Cap read resistance in BOTH directions by reversing the test leads on the terminals of the diode. One direction will read resistance and the other direction it will read open / infinity. Any other reading is a failed diode.

You check the capacitor using an analog (scaled vs digital display) ohm meter on R X 1,000 or R X 10,000 and watch for a jump on the meter just as you touch the terminals EACH time you reverse the leads. No jump or... steady resistance = bad Cap.

Sharp Capacitors can be found here:
http://www.repairclinic.com/Sharp-Microwave-Parts?s=t-FH-DZA119WRKZ-%3d%3db113a6c12

Just note that either a CAP or Diode failure can cause the main fuse to blow at the end of the power cord in the fuse holder.

Fuses are normally either 15 or 20 A Slo-Blo fuses and can be found here:

Sharp modelR1381 everything works but will notheat


If it runs and makes normal noise but just no heat, issues is either a loose connector to magnetron or at diode to capacitor. Be careful with capacitor because it stores thousands of volts.

Microwave display is very dim.


Replace the capacitors on the PCB that powers the LCD. Go to Digikey.com to buy replacements. Their parts are inexpensive and they ship fast!

Get a capacitor that has a higher or equal voltage (not lower!) and the same uF (microfarad). Also look for a cap that has a temp tolerance of 10,000 hrs at 105 degrees.

HV CAPACITOR FOR SHARP MICROWAVE


Sharp may not sell you this spare part as it is a high voltage saftey part. You would have to take the oven to a Sharp dealer to have it fitted. However, CPC Farnell in the UK may supply, but be careful.

NO HEAT


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

If it additionally does not spin and no light, then check also the door switch and fuse.

The diode and capacitors can br tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, even if power is off. Capacitors can get discharged by shorting their two contacts.
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. (here in UK).
