What People Are Saying

Rated 5 out of 5 by from First of all I have to say I have had an LG TV for 7 years and I love it . I ordered the LG Microwave and it is a good oven except, I am disappointed that it doesn't have a timer, also the vent is great but rather loud and I think you need to add a 1 and 2 minute cooking which was very practical

Rated 2 out of 5 by from Missing Coupler What is the piece called that the glass tray sits on to rotate? Is it a coupler that sits on the shaft that rotates the glass?

Rated 4 out of 5 by from timer I had several microwave in the past and in number pad all of them had a timer. separate timer. For example if I'm cooking something over stovetop and I need to time it " like alarm" I used to use the timer on the microwave, and this LG model doesn't have it. Also, light should have 2 levels: dim and bright.

Rated 3 out of 5 by from Disappointed Just purchased an LG kitchen suite, love the fridge, stove and dishwasher but am disappointed with the minimal features of this microwave. Did not pay close enough attention...everything else has LED blue lighting but microwave is green, no express cook buttons, and no timer. These seem like pretty basic features?!?!

Rated 5 out of 5 by from Microwave ease to use, lots of features and has a rack inside for double use

I am installing this on an inside wall under the cabinet. I rotated the blower unit so that the exhaust ports face the rear of the cabinets. Is this correct and okay

Asked by: acavano
I apologize, but no; it would seem that the proper installation for this ventilation duct would be to leave it rotated to vent back into the room, as it comes from the factory. In this manner, the ventilation will not overwork the fan motor, blowing air into a cabinet.

The fan constantly goes on and won't turn off when I try to turn it off unless I shut off the microwave all together. So I disconnected the fan. Is there any problem in that?

Asked by: Gegar10
We regret the trouble you have experienced with this microwave oven. The surface fan is designed to automatically activate if the temperature under the microwave reaches a certain temperature. This is a safety feature, and as such, the fan should not be disconnected or deactivated until the temperature is regulated.

The microwave oven came with a metal rack and rack mounts yet I see nothing in the owners manual about it or its use

Asked by: nestoavila
We appreciate your interest in this microwave oven. The use of the microwaveable rack is desired when cooking meats. Pages 21-23 of your owner’s manual recommend placing the trays of meat on the rack for best cooking performance.

How do i set a timer on this microwave? It doesn't appear to have this option.

Asked by: Ldgualar
Once the COOK TIME has been entered, you can use the POWER LEVEL button as a KITCHEN TIMER by entering a “0” for the Cooking Power.
