Question about LG 30" Over the Range Microwave Hood with Glide & Cook Tray, LMV1645S

Over the range microwave

I have the same problem. The microwave appears to be working until you open the door and take out your food. It doesn't heat up at all.

Can't get the micro to heat,everything else works

I had a similar problem but with another brand (Panasonic) microwave. Everything seemed to work, but the food did not heat up. I finally figured out that the problem was caused by a faulty door switch. I went to the local appliance repair parts store and got a new one, which fixed the problem. I don't recall the price of the switch, but it was in the $10 range.

Doesn't heat anything

It sounds like the micro generator has died.

Yes, you should buy a new one as the cost of repair is likely to be high.

My Maytag microwave stopped heating. Everything

Generally the magnetron (the part that heats the food) is the cause if everything else still works. Unfortunately replacing the magnetron is barely cheaper than buying a new microwave though you can check out repairclinic.com to decide whether you want to attempt replacing the part.

Let me know how this works out for you.

I have a 1993 GE spacemaker microwave/range hood combo. Everything works except that for most of the day it did not heat the food. The turntable still worked and the oven still appeared to be running. Then...

In short yes it can happen again.

Intermittent operation can be caused by a door interlock micro switch, a weak capacitor, an intermittent wiring connection from heat or poor connection, a marginally performing diode or a sticking Magnetron. Except for the Magnetron all other repairs would be worth the expense.

Repair costs and parts for most everything else will be between $65 and $100.00 depending on the part(s) replaced. Replacing the Magnetron would cost more than 50 % of the total unit replacement cost.

Microwave does not heat everything else works but does not heat

Same issues here, power up as usual, everything works except it doesn't heat. Usually when the magnetron kicks in, you know it because the unit bogs down from the load, well no bogging here just steady running of the fan. (Manufactured in 2007), do I detect a class action lawsuit in the works? I was fortunate enough to have purchased the extended warranty.

Repair man showed up day one with the most likely culprits (Magnetron & Diode), replaced them both and no help, there goes thanksgiving.

2 1/2 weeks later the tech showed up with a couple of (Micro Switches and a Thermostat), replaced those, ho help.

Now he suspects it the (PWB/PCB Power Control Board), because there isn't any power coming from the board to the tell the huge transformer to power up and sent the required voltage to the magnetron.
We will see when that is replaced if I'm back in business.

Just an FYI folks, if you're going to tinker with this use EXTREME CAUTION, as the transformer could put out upwards in the range of 4,000 volts, not to mention what the mag can do to you, so be SMART and be CAREFUL.

Comments: Dec 16, 2009 - Third time is a charm, the tech replaced the (PWB/PBC) today and we have a winner. That was the problem, either the Power Control Board itself or one of the relays on the board. Replacement was free because it was under extended warranty, but still reasonably affordable at repairclinic dot com ringing in at about $60. So good luck.
