PSB1000NBB01 General Electric Microwave - Instructions

Turned out the issue was easily solved by replacing a single, inexpensive fuse.

First off, UNPLUG THE MICROWAVE.

The fuse is located under the plastic grill at the top of the microwave. It's held on by two screws. Once you've removed the screws and taken off the plastic grill, you go to the right side of the microwave and remove another screw that holds a small metal grill in place. Removing the small metal grill is probably the toughest part of this repair. You kind of have to rock it back and forth a bit to get it to release. Once that's off, you can get to the fuse. I removed the burnt out one with a pair of needle nose pliers. I also put a small piece of cardboard under the fuse when I did this so I didn't accidentally drop it into the innards of the microwave. I did the same thing when I replaced the new fuse. I then plugged the appliance back in and made sure it worked. Once that was confirmed, I replaced both grills.

Turned of f the circuit breaker to the microwave. Unscrewed the cover (1 screw!) popped out the old bulbs and plugged in the new ones, using the bubblewrap as a handle to be sure my skin didn't touch the light bulbs so the oil from my hands didn't damage or shorten the life of the new bulbs. Turned the circuit back on. That's it!

Unpluged power cord!! Removed front control panel to expose electronics (need to remove top horizontal vent cover to expose mounting hardware). Unplugged leads to control panel board. Removed magnetron with Tstat (3- phillip heads, need stubby). Installed new parts and control panel, plugged it in tested. Done.

The old fuse is perfectly good. The new ones arrived within a day.

1. turned off electricity -- unplugged the unit 2. removed 3 screws on top of top vent, removed vent screen then I located the little white cylindrical fuse and popped it out with a table knife. Then I popped in the new fuse. Replaced the vent screen and screws -- plugged in the appliance and it is working again.

This is the second time that this lamp hase gone out. It is located in a small space in the top of the microwave and you need to remove the top front pannel, then take a screw or two out of a metal shield and bend the shield up to get your hand into the compartment where, if you know how, you can reach in and lift out the reflector shield that the lighbulb is plugged into and remove the old one and plug in the new one. The first time was hard to figure out how to do it but the second time wasn't bad because I knew how to do it.

*Remove Two Phillips head screws from the top of vent slide the vent left to remove it. Take the charcoal filter out then the metal cover underneath the filter. It also has a phillips head screw. bulb socket is on right facing down. Squeeze the metal clips and remove socket from bracket. Installation is the reverse of removal.

After removing the screws holding the 2 cover plates in position, I removed the halogen light bulbs with my fingers. Then I placed a paper towel around the first replacement bulb and lined up the two wire connectors with the two holes in the receptacle. I pushed in, but the bulb's probes did not slide into the receptacle. I spent five minutes aligning and pushing but to no avail. Then I removed the filter screen on the side of the receptacle, shined a flashlight beam on the receptacle, and with an improved view of the two holes in the receptacle, slid the bulb in. The second bulb was inserted in a few minutes, and the job was done. Whoever designed the halogen bulb was not as bright as Thomas Edison.

This did not fix my problem. I've ordered a new microwave.

First and most important - unplug AC power 24 hours before service.

I removed the vent cover above the main door, then I removed the screw which holds the control panel in place, unplugged the main connector on the control panel so I would have enough room to work, removed grounding screw from the DIODE ASSY, pulled connector off the CAPACITOR with pliers, installed new DIODE ASSY.

After installation of DIODE and the control Panel, I plugged in the AC power and allowed the CAPACITOR to charge - this takes about an hour or so, then test. Works perfect!

Went to onlin source, found a couple youtube videos then went to the GE site which had a not-too-easy that find trouble shooting guide. It was extremely helpful as it described a fuse as a fix 80% of the time for touch paid failure. I really didn't believe it would b a fuse, but it was the cheapest fix, $8. I got the fuse and was surprised to fine there are two of them on this model. I took a guess and replaced the top one ( neither fuse was black or burned to indicate a failure but the top one was a bit mor greyish). put it all back together and it works fine.

took off upper grille and touch pad and removed the old line fuse and replaced with a new fuse ...turned on it is working fine...sources of help: UTube and GE manuel

Turn off the circuit breaker to the microwave. Remove the 4 black wood screws that secure the microwave to the cabinet. Pull the microwave all the way out and set it on something that leaves you access to the middle access panel on the bottom. Remove the access panel on the bottom that has one screw. Unhook the 2 cables to the motor remembering which color goes where. Remove the 2 screws for the motor and replace the motor. Finish up in reverse...

Replace Advantium 120 flashing display.

Step one: Disconnect the power to the Advantium 120. Unplug unit, trip the breaker, whatever. Your responsibility to make sure the electrical power is removed.

For cabinet mounted units remove four screws from front side flange holding the microwave to cabinet

On the cabinet mounted model access three screws along the top front edge of case behind the display then one screw on each side of display and two hidden screws accessed through the top of the case via access holes. (use a magnetic see driver for these screws)

Work the display panel off and support it until the connectors are removed.

There are three small color coded plugs on the left side to the PC board and five larger colored plugs on the right side. Note plug locations.

Lay the removed control panel upside down on a towel at the corner of the sink so the selector knob is not resting on the counter.

Remove PC plug to the display and remove four screws on the PC board. Shift the PC board to release the tabs. Then remove two screws holding the PC display board. Note two guide pins also align the PC board.

Remove the rubber insulator from the old board and put it at the same location on the new board. There is usually enough stickiness on this insulator to put it back on the new board.

Installation is reverse. Reconnect power. Try it out after completion by boiling water in a microwave safe container. My new display was much brighter than the replaced display. No flashing.

1) Removed 4 screws securing the microwave to the cabinet.2) Slid microwave out, unplugged and placed on a work surface that allowed lower trim to hang over. 3a) Removed two screws and removed the cover on top of the oven. 3b) Unplugged high voltage plug from Magnatron. 4) Removed wires from overtemp fuse mounted to Magnatron. 5) Removed the four screws securing the Magnatron to the oven. 6) Removed Manatron. It's a tight fit, but can be done without removing anything else. 7) Replaced Magnatron. This is where I needed the magnetic part retrieval tool. The nature of a Magnatron is the use of strong magnets surrounding the tube. Getting the four screws back into place wasn't possible with just a normal magnetic screwdriver tip. I used the retrieval tool to position the screws back in place. Be sure to not initially tighten any screw completely, until they can be evenly tightened. This ensures correct compression/seating of the shielding material near the neck of the tube. 8) Reverse removal steps. Plugged in and tested microwave function on a cup of tap water. 9) Reinstated in cabinet and got a big thank you kiss from the wife!
