Question about LG LMV1813ST Microwave Oven

Open Question

LG microwave - does not heat food. Light is on, turntable turns, you can hear the fan and the magnetron. Called LG help line and they said it is probably door latch. How do I fix that?

Over the range model. Purchased 11/2011. Installed and in use since 3/2012. No extended warranty purchased.

SOURCE: Will not heat.

Hi I've been out of the microwave repair business for a few years now, but the technology has remained virtually the same as far as I know. You obviously have some knowledge of them, as you know about the safety switches in the door. Microwave ovens are actually a very simple device, to test it, put a coffee cup of water inside, and set the unit on high for one minute. A second or two after you hit the start button, you should hear a fairly loud "bong" noise, and a hum that continues untill the time runs out. That noise is the magnetron starting up, and if that noise does not happen, then the magnetron or related circuitry is probably bad. NEVER open up the oven, as the magnetron may be charged, and must be discharged by a technician. If the sounds that I described are present, then the water should be boiling or close to it in one minute, if not,then something I've never seen has gone wrong. Assuming you had a year warranty on it, I know from experience that if you contact Goldstar customer service by phone, or letter, they will often extend their warranty a month or so to keep happy customers. Its worth a try. Hope this helps you out. P.S. Never operate a microwave without something inside (Non metalic)

est the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.

Thediode and capacitors can br tested. The capacitor must bealloweddischarge before testing, or you risk to get electrocuted, evenifpower is off. Capacitors can get discharged by shorting theirtwocontacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.



All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, contact the seller here to purchase parts.

I purchased a house w/ a Jenn-air elect. drop-in range. The Model # is 87946 or 87847. I believe the range was originally purchased in 1975. I am in need of an instruction manual .


Neither of these are a typical Jenn-Air model number. http://shared.whirlpoolcorp.com/product_literature/search.jsp?siteCd=JA_EN_US suggests that the model number is on the back wall under the burner on the right side of a drop-in cooktop. For a range the model number is often on the frame inside the oven door, below the vent or on the back of the top of the range.

87946 or 87847 are the part numbers for the cartridges (the elements or the surrounding housing).

Look at the model number locations at the "Help me find my model number" link and try to locate a model number on your range. Then enter that model into the search box. The manual is probably available with the correct part number. Most Jenn-air electric cooktops start with JEC in their model number.

I hope this helps you locate the manual.

GE microwave model # JES1855PBH 04 .This was purchased less than a year ago. It just stopped working.Will not do anything,does not even light up controll panel.


First, check your circuit breaker to see if the circuit may have flipped off. If it isn't off...

Lucky for you that this item has a one year warranty. Look at the second to last page of the instruction manual and follow those directions. If you bought it using a credit card, have the receipt and the original manufacturer's warranty is out, call the credit card company and ask them if you can make an extended warranty claim. They will usually double the manufacturer's warranty.

How do i get extra warranty


An extended warranty is normally offered by a retailer at the time of the sale. With some products such as cars, computers, and televisions, there are companies that will sell you an extended warranty as long as you purchase it before the manufacturer's warranty runs out. There are a few manufacturers that will sell an extended warranty to an owner of their product, but, once again, it has to happen before the original warranty runs out.

Contact the manufacturer and ask if they offer extended warranties. If they don't and you're still within their warranty, visit the link below. They offer extended warranties of 4 and 6 years for appliances.

Usually you must purchase the warranty within some specified time of the purchase, such as one week.

But your best bet is to contact the dealer where you purchased the unit. If they are able, they will be eager to sell you an extended warranty.

We're happy to help and we appreciate your thoughtful rating of our answer.

I junked it and will never buy another GE product. The repair people cost more per hour and that was their advice also. I purchased another microwave with an extended warranty. Lesson learned.
