Hi bought this a few years ago and never installed it until a couple days ago it seems that everything seems ok until I treid to warm something but nothing happens. It's still cold. What could it be?
Answer Hello Speedy. You most likely have a "high voltage" side malfunction. Transformer, diode, magnetron, Capacitor. You will need to be extremely careful if you decide to test the components with a multi meter, Very high residual voltage is present, so make sure you remove power to the microwave and short across the terminals on the capacitor. The magnetron should have a reading of less than 1 ohm resistance across the two terminals, and an "open" circuit between each terminal and chassis ground. The diode/rectifier should have a resistance reading in one direction only, no resistance, or resistance in both directions indicate a faulty diode. The primary winding on the trans former should read approximately 450 Ohms resistance, the secondary winding should read 80 ohms resistance, and the filament transformer should read 100 ohms resistance. If all the readings are proper and in range, replace the magnetron.
Good morning. I have no power at all to my Whirlpool microwave model number GH5184XPB-3. Can I access the fuse without removing the entire unit from the wall and removing the entire cover? Thank you in advance.
There is a ceramic fuse that is located behind the control panel that you can test to see if it is bad. You would remove 2 or 3 screws from the top of the unit that holds the grille in place. Once the grille is removed you would remove 1 screw that holds the control panel in place. Test the fuse for continuity. If this fuse checks ok then you will need to pull the unit and check the cavity thermal cutoff.
I was changing out the light bulb under the microwave that light up the stove. It cause the bulb to short out and now the microwave itself doesn't work. What can I do?
Answer Hello Keith,
This could be a fuse, low voltage transformer, a wire shorting to ground, a bad light socket shorting out, or a solder connection you heard pop. The unit will have to be opened up to check for the issue.
my accuwave microwave oven wont heat things up. tray turns, it counts down like it should, and when i try to use any of the automatic sensor functions it stops and displays -F3H- . also the fan no longer works.
Answer Hello Al,
The F3H error code indicates a humidity sensor failure. To test you will need a good sensor and control board. You will unplug unit and connect sensor to P5 on the control board. Plug unit back up. If the error code does not come up then install the sensor. If error code returns then replace control board.
Our microwave stopped working about a week ago. Nothing on it works, not lights, switches, nothing. We checked the basement fuse box and it is fine. I believe it could be the fuse inside the oven. How do we get to it and replace it? Need detailed instructions, thanks!
Answer Hello Pam,
To replace the fuse you will first unplug unit. Once unplugged there are 2 or 3 screws on the top front of cabinet that hold in the grill. Remove screws and grill. Once grill is off then there is one screw at top of the control panel. Remove screw and control panel. Once remove you should see a buss fuse. This is a 20 amp fuse. You can pull this out and test for continuity on it. If there is no continuity then you would want to replace the fuse. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
