SOURCE: Cannot heat

Sounds like it overheated, tripped the thermostat, then the thermostat reset. Chances are you have a bad magnetron. GE may have a campaign (not a "recall", mind you!) to offer free replacements if yours is a model that has a known history of problems with the magnetrons. I would call GE and ask them about that. *grin* GE Answer Center 1-800-626-2005 24 hours a day, 365 days a year

SOURCE: NN-T990SA Panasonic Microwave Stopped Heating

This model uses an inverter to produce high voltage instead of a convential transformer system. While an inverter (switched-mode power supply) is more efficient from a power consumption standpoint, it is more complex, thus more statistically prone to fail. These should only be examined and worked on by someone who has the necessary technical qualifications. Seriously. Often the machine-soldered connections in a microwave inverter are too weak, so they eventually fail, especially if heat is high in the area. They sometimes fail catastrophically. When not catastrophically damaged, you may hear clicking or squealing and may smell an electrical odor, which is sometimes obscured by the cooling fan. Some manufacturers do not encourage or assist technicians to repair microwave inverters. Most offer the inverter as a whole assembly. But sometimes that is actually cheaper than the time and labor required to fix the old one. If a technician is willing and able to troubleshoot and repair the inverter to component level, it will may be expensive, but may be worth it, especially if he or she will resolder and reinforce connections as needed as part of a thorough repair. That could easily make your inverter beter than a new one! You might be able to get some verbal estimates if you call Panasonic-authorized repair shops and ask then specifically about inverter repair and inverter replacement costs for your model number.

GE had a rash of "underperforming" magnetrons on these units. They replace the magnetron, stirrer and high-voltage diode at no charge for parts as long as a GE-authorized service center does the work. Sometimes the unit gets run too long in a failing state and the waveguide and chassis of the oven get damaged. To see if yours is covered, see this bulletin: http://www.microwavedisplay.com/ge_mw_mag_kit_bulletin.pdf Otherwise, you need to contact GE Customer Relations at 1-800-386-1215 as soon as possible and tell them your problem and they will put you in touhc with a local authorized servicer.

SOURCE: No power from Whirlpool.

The problem was a defective switch. There are 3 switches on mine. 1 on the top door latch, and 2 on the bottom. one of the switches on the bottom connected the power and neutral together, unless it was activated at the same time as the other 2, causing the breaker to trip or the internal fuse to blow. When unhooking the wire going from this switch to the other switch, everything works great now. Though I still need to replace the switch.

And for Basic 1. Yes my microwave did have a fuse in it it's ceramic, I got a pack of them at Radio Shack 4 for 3$ 250V 20 Amp. There should be a wiring diagram inside the microwave, mine was inside a black bag, so it may be hard to see.

Mine was up top next to the fuse behind the Plastic Grill and then a small metal grill. Some are behind the control panel, to fix this remove the screw at the top and then slide the control panel up and it should unhinge.

My child lock on my Frigidaire is constantly beeping... The door is not locked but it is beeping...


Hello Shelley, thank you for your inquiry!

I understand your Frigidaire is constantly beeping while they door is unlock, however do you have a range or microwave Frigidaire appliance? The serial tag for a range, which lists your model number, is typically located in the storage drawer, on the right side and the serial tag for a microwave is in the lower left corner as you open the door. With this information I can better address the issue at hand. Thank you!

Where do i find the serial number for this range


If there is no label on your microwave's inner wall, consider searching online within the manufacturer's website. Model and serial numbers can be found at the rear of most microwave ovens.
Hope helps.

I have a microwave range vent and I need the installation instructions for it.


Hi. These unit were made by Samsung exclusively for "The Brick" In Canada They have their own model numbers other than the usual Samsung model numbers. I did my best to try via samsung global but no joy. The best I can tell you is to call them and ask for the manual: (have your BMHC815SS model number ready.)
