Powers off immediately after starting


My immediate reaction would be to cut your losses and buy a new unit as sooner or later you will run into a part that is no longer available.

No power, fuse good and breaker fine any ideas


Hi

You can test the door switch, if the door switch tests fine then it is the control board that is bad and if the unit is too old then its better replacing the unit completely as the control board will cost you around same as new one. Hope this helps...please post back for further assistance.

I have a ten year old Amana bottom freezer refrigerator bx21v1c,and the compressor has died. I am debating as to whether to buy a new refrigerator or to pay up to $800 to replace the compressor.


Hi,
There is no way that I would spend $800.00 on a ten year old fridge... I can do my own and I would not replace a compressor on a ten year old unit...too many problems afterward...too many other things that could go wrong shortly...

You will be better off to take the $800.00 and put it towards a new unit...

I was heating my tea and I heard a loud pop and the unit turned off...I thought I had blown a fuse and went out and checked fuse box..flipped all fuses and microwave still not turning on at all...micorwave...


The description you provide indicates the magnetron has failed, "heats food" and blown the main fuse in the microwave oven, since the unit is 10 years old it is much cheaper to replace with a new one rather than have it repaired.

Can i get a display screen for a sharp microwave model # R-530ES, and if you can provide this display, can it be shipped to miami?


The relevant service manuals are HTML clipboard here and here. hey contain detailed disassembly instructions.

There are three ways to get this fixed:

1. You could order a new power unit (lower board assembly) and a new upper display board assembly, solder them together, then replace your assembly with the newly assembled one.

You'd need the following parts:

DPWBFC167WRKZ CPU/LSI/display unit $107.07
DPWBFB094MRU0 power unit $53.09

Which can can be ordered from Encompass here.

2. This option is more difficult, but cheaper. You would order the upper circuit board assembly, desolder your old one from the lower power board, then solder the new upper board onto your power board.

You'd only need to order this part:

DPWBFC167WRKZ CPU / LSI / display unit $107.07

3. You could send your control panel assembly for repair for $39.95 with a one-year guarantee. Details are HTML clipboardhere.

Fan runs when unit is off


The control relay has gone bad, to replace this if you can find the board runs about $195.00, I hate to say do not repair something but in this case, I would have to say it is time to retire this one.

Display fully lit (all characters) @ plug in but unit not running


I'd say you have a bad keypad, or possibly a problem on the control board.

But with the cost of a comparable unit ($85 at Wal-Mart), it may not be economical to repair.

It would run $39.95 if we just repair the board, or about $50 if you replace the keypad frame assembly yourself.

Spending a little more would get you a new oven with a warranty.

F9 error


Your Microwave uses "UltraWave technology"
I'll explain a few things about this wonderful technology...
The control board (accepts the pushbutton commands) has to talk to the inverter board to tell it how much power should be applied to the magnetron. The inverter board will then power the magnetron and inform the control board if the magnetron is working OK.
If there is something wrong with the magnetron or inverter board or a there is a communication breakdown between the control board and the inverter board...WA-LA-----F9----

A pretty reliable test for the Magnetron is to operate the oven and listen for a ticking sound 5-6 times about a second apart. If you can hear the ticking....The magnetron has failed..if no ticking, the control or inverter board failed.

The Magnetron sells for about $78.00 and is simple to replace. Check your owners manual for limited warranty on the MAG and electronic parts.

GE Profile Spacemaker II Microwave won't beep


hi,

The control board may need to be replaced, check your records to see if the unit is still in warranty, if it is call for repair. If it's not and you’re handy, you can find the part online and replace it yourself, just make sure you unplug it before you work on it. Please contact me if you need help.
