CTC912P2N1S1 General Electric Microwave - Instructions

TERRIBLE!!!!!!!
FIrst part arrived broken
Second part arrived broken
Third part arrived broken
Finally on the 4th try, the part arrived and was not broken.
I will NEVER again order parts from this company.

Followed the instructions on your website and a YouTube video. The diode was at a 90 degree angle which made it a little trickier. Unfortunately the repair did not resolve the problem. I ended up buying a new microwave for temporary use for less than ordering any more parts. We are pleased with your website, instructions, ease of installation though!

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

Microwave with no heat. Removed casing and checked low voltage side from the fuse through all the microswitches to the primary side of the transformer, all good. Checked HV diode good. Checked secondary side of transformer, good. Checked capacitor, good. Even though the Magnatron electrically checked out good, it had a cracked magnet. Replaced the magnatron and we have heat again!

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.

Step 1, turn off circuit breaker, verify no power at the back of oven

Step 2, remove oven from wall/housing by removing 4 mounting screws, 2 on each side, just on the inside after opening the oven door...this was the most difficult part doing the repair on my own as the oven is a bit heavy...I was fortunate to have a old Workmate 425 work bench that folds/collapses, this allowed me to slide the oven out and drop down about 2 inches...reinstalling the oven I did have to use 2x4s to shim the oven level to slide it back in, with someone to assist this would not be necessary.

Step 3, remove covers to gain access to the blower and sensor

Step 4, remove the sensor

Step 5, install new sensor

Step 6, turn on the circuit breaker

Step 7, test the oven (success, Y, turn off breaker and reassemble all covers, install the oven, secure with the 4 mounting screws, turn on circuit breaker, test one more to ensure of proper operation...N, go to step 8

Step 8, turn off circuit breaker, reinstall original sensor

Step 9, remove blower

Step 10, install new blower

Step 11, turn on circuit breaker

Step 12, test oven, problem resolved, Y, go to step 13, N, continue troubleshooting.

Step 13, turn off circuit breaker

Step 14, replace all covers and reinstall oven, secure with 4 mounting screws

Step 15, turn on circuit breaker

Step 16, test, still operating properly Y, receive hugs and kisses from wife, N, do not make eye contact with wife, take dog for a long walk.

Very straight forward repair except for removal of the fan mount plate. There are 4 sheet metal screws, 2 of which are obvious and shown in the appliance diagrams, and 2 of which are neither on the appliance diagram nor obvious. These screws are beneath the motor assembly and oriented with the heads between the mounting plate and the top of the oven - about a 3/8 inch gap. Removal was accomplished using a 1/4 inch open end wrench strictly by feel as there is no sight line. Not all that challenging, but still a pain. On reassembly, these screws were reversed so that the head is now on the top of the plate and more accessible.

there was one screw holding it on the back wall of the oven. It was easy enough that my daughter installed it with my guidance.

taking the oven out of the wall the most difficult part.. once you removing the sheet metal screws....be sure to take pictures as you dis-assemble putting back together will be easier. wait for correct part. second try they sent the correct part. put back together, test before putting back into wall.. big savings by doing it yourself.

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!

So my microwave was turning on and operating but nothing would get hot or even Luke warm. After watching several online videos on the problem I replaced the line fuse, diode, and the magnetron. I figured why waste time and just do all 3 while I have the thing apart. I discharged the capacitor with a light bulb first before doing anything. Also had to pop the safety pins on the outside screws to take the metal housing off the microwave. Then Wallah! Everything is working and the food or liquid is hotter than it ever was. The only think that bothers me a little bit is that after the microwave shuts off, I can hear a few crackles or faint pops for about 5 seconds. I wonder if this is anything to worry about. Comments appreciated.

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.

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.
