Unfortunately you will not find anybody that will give more than year on the magnetron and labor is usually 30 to 90 days. There are two ways to go, get appliance repairman, or a tv technician, rates will vary depending on who you call in to do the job, but! in general the repairs for parts and labor will run more than a new microwave oven.

HVM1750 won't heat

The magnatron is likely to be the problem... though I have seen the fuses go , they usually follow the magnatron.
If your unit is under 5 years old , the Mag is covered under warranty and all you need to do is contact GE at

with the serial number of your unit and they will send you the replacement magnetron imediately and free of charge.

You are responsable to have the part installed , but there are videos on Utube that will walk you thru it no problem.

Which is a wiser choice. To buy a microwave with a 1 year warranty or one with a 1 year limited warranty and a 5 year limited magnatron warranty? Thanks

I would buy the microwave oven that has the one year warranty because it covers your purchase 100% If you buy one with a one limited warranty you need to read the fine print what it does not cover, and the magnetron with a five year limited warranty sounds good but has restrictions on the actual coverage, meaning they can refuse the claim by saying it does not meet the criteria, because the "claus limited" has been put into place and is misleading.

Power works, everything seems normal but no heat

microwave ovens do not produce heat, they produce microwaves. the heat comes from whatever is excited by the microwaves. In your case i would bet that the magnatron (microwave tube) has become defective. If this oven is less than 5 years old, the magnatron may be under warranty. depending on the model it may be repaired at no cost to you. In the case of Kenmore (Sears) you would take the oven to their customer service dept and they will send it in for you for evauation. they will charge you $50.00 US this amount will be applied to the repair if you choose to have it fixed. If the Magnatron is bad and is under warranty, they will fix it, and return it to you along with a refund of you $50.00.

Everything else seems to work fine but when I take

Magnatron has failed, possible internal fuse to the Magnatron,or the Magnatron itself has gone bad.
Both are replaceable, but the microwave will have to be taken down to gain access to these parts to be serviced.
Now, depending on the age of the unit, it may not be wise to invest the cost for this repair, unless, is it still under the manufactures 1 year warranty or did you purchase an extended service contract on this unit?
Good Luck !

My LG microwave is no longer heating up food. LG Canada advised I need to order a new magnatron. Since it is no longer under warranty, it will cost me $66+ shipping to order the part. Is the magnatron...

It can be somewhat tricky and dangerous if you are not careful. Unless you are capable of working around high voltage and able to re assemble something with lots of carefully fitted pieces I would let a trained professional do this job.

All sounds and looks fine but no heating going on this 5 y.o. samsung microwave. If it is door switch (any one of 3 I believe) how to check or if magnetron I'd think I'd have to throw away...Advice?

It's most likely the magnatron. If it sounds good it's not the switches, transformer or diode. If you still have the book for it, a lot of magnatrons are covered under warranty for 5 years. Unless it's a real nice microwave, it's usually going to cost $100 for a mag and nowdays it's almost cheaper to get a new one. Good luck

Whirlpool MH1150XMQ 1000 Watts Microwave--NO HEAT

About 95% of the time it is the magnatron. If the microwave is under 5 years old that part is often covered under warranty. I would check your manual. If not the p/n is 8206335 and it's about $80 and fairly easy to install. I just looked and the magnatron is covered.

Labor to replace it would be about $125

Hi, I have a big over-the-range GE microwave installed in my kitchen near my prep sink, not over a range. After I had it for 2 years, I received a letter from GE that there was a problem with the...

Microwaves usually have several years' warranty on the magnetron itself - such as 5 to 9 years!

I would call the GE Answer Center with your model and serial number and ask them how many years the magnetron is covered under warranty.

Also ask them for the numbers of a few local GE-authorized warranty service centers.

(GE Answer Center® 1-800-626-2005 Open Monday 6 a.m. ET through Saturday midnight ET)

If the mag is still covered, and you take it to a GE-authorized warranty service center, you'd not have to pay for the magnetron.

And taking it to the shop will indeed save you a lot of money.

If you decide to remove it from the wall, the installation instructions will be very handy to have. If you don't have them, you can find them online here.

Good luck and be safe!

GE JVM1650

The owner's manual will give you the warranty length. If you don't have yours, you can find it here:

You really need to call GE on this. Only they can answer if they will still cover it. GE Answer Center -800-626-2005, 24 hours a day, 365 days a year.

Otherwise, it may fall under your State's lemon laws. You can contact the Attorney General's office, usually via (where xx is your State's 2-letter abbreviation).
