PSB9120EF1ES General Electric Microwave - Instructions

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!

unplugged power cable / unhooked front vent / unscrew the monitor panel / slide up to dislodge / take the fuse out and put in the new one in / fuse is located right in front of monitor panel once its open might be covered by wirings / you can unpin the cables from the panel to make it easier for you just make sure to put it back properly or you can have somebody hold the panel for you. Installing the fuse is easy waiting for the parts is crazy......

One small Phillips screwdriver and one fuse puller (I used cord). Unplug unit. Remove the two screws on the vent face plate. Remove the one screw on the panel assembly. Gently let hang. Pull the fuse located on the upper left wall. Replace fuse. Reassemble.

First remove all screws holding on outer metal casing of microwave. Next remove the back and bottom metal pieces. You will then be able to pull aside the outer casing so you can access the door switches. Check each switch with an ohm meter in both the open position and with the switch closed. If the ohm meter reads the same in both the open and closed position, the switch is bad. Check the top switch first. Replace switch and reassemble. Cheap fix for a costly microwave. Great customer service at Parts Select!

I looked at the exploded pic on your web site to find the location of the sensor. Next I removed the cover by unscrewing 15 screws then swaped the sensor and re assembled! Works great! Fixing it my self I saved at least 150$ and did not have to wait all day for a repair man who probaly would not have the part on the first visit.

Symptom: Terrible sparking coming from the right side of the microwave even with nothing in the microwave. The part that was behind the cover was the business end of what I learned was the magnetron,

Repair process: Without appliance repair experience I went onto Google and searched for parts for my model PEB1590DM2WW. I was able to find a great parts schematic on partselect.com. At first I ordered a magnetron and while waiting for the parts to arrive I also learned that the capacitor can also fail easily as described in the other install feedback on the partsselect website. So I ordered a capacitor just in case. These convection microwaves are around $600 new so a $80 in parts is not out of line for 8 years of service.
I installed the magnetron first and turned it on. sparking immediately continued so I quickly shut the unit off. After replacing the capacitor and letting it charge for several minutes before trying to start the microwave cycle was the issue. I choose to leave the replaced magnetron as the original unit was discolored and felt the replacement was inexpensive insurance. I also learned that if the wave guide (which is a plastic/metallic composite material) that covers the opening to the magnetron is burnt or has metal melted to it as mine did it will act similar to the microwave having metal inside the enclosure and will continue to spark and basically melt the wave guide further. Replacing the wave guide was very easy as well.

I am very thankful for the knowledge base and support available from Partselect.com as they made this repair possible on my own. Thank you partselect.com

It is easy to repair the burnt out bulb if one has the correct bulb. Your website is very user friendly and your service is great. I was not able to replace the bulb at this time because our RV is at the repair shop for some other matters. I am sure the installation of the new bulb will go smoothly. Thanks for asking.

Everything worked on the display light inside worked but when you closed the door and set time it would start counting down but not heating nor would the turntable turn. Started reading troubleshooting chart and first thing I did was removed the cover and checked door switches and found primary door switch wasn't working so I ordered a new one installed it and it worked. Anyone doing this has to be very careful because of the stored energy in the capacitor is strong enough to kill.
My micro is only 2 years old so I was hoping it wasn't anything major.

I removed the main cover ( torx security bit required) and tested the magnetron, capacitor, diode and door interlock switches according to instructions found on the internet. The capacitor and diode tested good but the magnetron looked burnt and corroded on the tip. The magnetron I received was an exact replacement for the original. It was easy to replace the magnetron which arrived in 2 days standard shipping. I also cleaned the fan while I had access to the inside area. Hoping to get another 18 years use from the microwave!

I REMOVED THE TOP PANEL OF THE MICR0WAVE AND THEN REMOVED ONE SCREW TO REMOVE THE CONTROL PANEL. rEMOVED OLD SWITCH. SNAPPED IN NEW SWITCH AND CONNECTED WIRE. REPLACED CONTROL PANEL AND UPPER PANEL.

I did not have to replace the part. I turn the fuse off and waited 5 minutes and turned it back on. The display came back on. I saw this recommendation on your web site after I ordered the part. You should do this before you order the part.

Very easy to replace. This replacement part is the perfect fit for my microwave since the original part has been discontinued. It does have the night light and bright light feature.

Check with Digital meter all connections.Find a Thermostat open loop.This thermostat is near the Megatron .

Removed the old canopy mica, it has tabs that slip into slots on the top of the microwave. Then installed the new part, the tabs are inserted into the same slots.

DISCONNECT THE POWER CORD and discharge the capacitor
Leave unplugged overnight
Remove vent grille by removing the 2 philips screws
Remove the LED panel by removing 1 phillips screw
Disconnect all connectors that plug into back of the LED board completely
Remove the wires from the switches (3) at the inside edge of the microwave door
Gently remove each switch housing and test all three switches for continuity
Carefully replace non-functioning switches and reassemble the panel
GOOD LUCK
