CVM1790SS4SS General Electric Microwave - Instructions

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.

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.

Parts arrived on the morning of the second day (Saturday) to my pleasant surprise. I opened the nite light access door with a screw driver. Inserted the 2 bulbs without touching the outside of the halogen bulbs. Checked that the bulbs did work and closed the access door. The entire process went quickly and posed very little difficulty.

scape melted plastic off of oven wall. apply pliers to melted plastic, pinch plastic, and turn one quarter turn and remove. grab new rack holder with pliers, insert into hole and twist one-quarter turn

Removed unit from above range. (A two person task.) Removed display panel, disconnecting wires from plugins. Removed outer cover to access magnetron. Used camera to take photos before disconnecting other wires. Replaced magnetron and reconnected wires, double checking with photo. Tested prior to reinstalling. It works fine.

removed screw that holds glass for light and replaced bulb.
Reinserted screw that holds glass.

Only down side was cost to ship small bulb.

I had already removed the old grease filters. Unwrapped the new grease filters and popped into place. No tools were necessary.

Removed the light cover screw with a Phillips screwdriver. Removed the lamps from the packaging just enough to free up the 2 prongs for fitting in the socket. Make sure the power is in the "off position". Install the bulbs one at a time by lining up the 2 sockets (Very important not to touch the halogen bulb glass surface while installing them). Energize the light switch to check operation of the new bulbs.

My oven is installed above the counter making it a bit difficult to reach the screws closest to the wall. Instructions should note that both harnesses need to be disconnected and that there are two screws, not one holding the motor. This one issue made it frustrating since that screw is located towards the back away from your vision. This is when the flash light and a bit of contortions were required.

This is an above the range microwave, use 2 people to remove it. I set it on a table and removed the outer cabinet. I then used jumper leads to discharge the capacitor. I removed the control panel (taking a picture to ensure proper wiring on assembly), then I removed the latch board. Once I had the latch board out I removed the monitor switch (which is the middle switch) and tested it for continuity. This is a normally closed switch. I tested the other two switches as well and found these (normally open) switches for continuity to be good and the monitor switch to have a short. This switch should show continuity when the door is open and should show no resistance when the door is closed. (Take care removing the switches) After I received the parts I installed them in the new Locker Holder and installed the latch board (ensure to follow the latch board adjustment steps located in the control board). I then attached the wiring to the control board and then plugged in the unit. I tested the unit to ensure it functioned correctly. I then installed the outer cabinet, and then installed the unit above the range (Use 2 people for this process). Overall an easy fix you just need to ensure you follow safety procedures (especially when dealing with capacitors.
Take a lot of pictures of the wiring and of the components and take care with the latch board or you'll have to buy a new one when all you really needed is a monitor switch.

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

To get the microwave out to fix it, Appliance repair man had to dismantle surrounding Cabinetry. It then took him half an hour to replace part. Reassembly took another 45 minutes.

Remove the ice bin.
Turn the ice maker selection to "OFF"
Use small flat blade screwdriver to open the plastic ears on the electic plug in connectiion
Use #2 Phillips screwdriver to remove the screw on the front left side of the ice maker
Pull the ice maker forward until free of the two studs in the left side rear of the freezer wall
Check to see if the supplied water chute is the correct size for your application, if not remove the water chute from the old ice maker and place it on the new one.
Place the new ice maker in the freezer connecting the slots on the left read with the studs on the left wall
NOTE; IF THE ICE MAKER DOES NOT APPEAR TO BE LEVEL HORIZONTALLY REMOVE IT AND CAREFULLY REINSTALL IT TO ACHIEVE LEVEL
NOTE: ENSURE THE WATER DELIVERY TUBE RESTS IN THE RECEIVER TRAY
Reconnect the electrical plug ( needle nose pliers may be helpful in aligning the male plug with the female plug)
Move the selector from "OFF" to "ON"
Replace the ice bin and close the freezer door

I replaced the TCO (fuze) through the vent opening after removing the vent cover and several small panels with a screw driver for visible access.. Some of the screws require a small offset screwdriver because of the limited access. I did not have to drop the unit from the wall over the range and was able to access through the vent opening to replace to failed TCO with a new one. The TCO is wired in-line with the power and other fuses to the unit and when it fails the enitire unit is cold with no power to lights or function of any kind. The GE service rep. said that the unit needed a new smart board but that was not the problem and they are no longer made for the older unit. I discovered the repair by looking at YouTube for repairs for the GE Advantium 120 microwave/convection combo unit.

Remove upper grill, then control panel, then 2 screws hold door switch mounting bracket, that will let you roll the switches out to work on them. Remove each switch by carefully pushing back retainer clips. Diode a long pair of needlenose pliers is helpful. The control board in front of capacitor comes out with a flat screwdriver and pry up. Removing grnd wires helps
