Samsung mw87L microwave does`nt emit heat, light works, turn table works, controls work, but no heat. Had it just over a year.

First, check to make sure that the door is closing and latching fully and that there is nothing jamming any of those mechanisms. There are safety devices that keep microwaves from turning on if they think the door is open/ajar.

If the door is fine and the rest of the functions (timer, etc.) are behaving, it's probably a busted magnetron. That's the part that actually emits the waves that do the heating. It's a part that can be replaced, but probably cheaper to get a new microwave.

Repolace the microwave, the heating components like the magnatron would cost almost as much as a new microwave. If money is an issue try Goodwill, they usually sell microwaves for about 5-10$ which is WAY less than cost of parts.

it sounds like it one of your micro-switches inside that control the power to the doors, if one of the switches is bad, it would cut the power , the panenl will light, the turn table will work, the fan will turn on , but you will not get any heat at all, micro-switches run depending onthe unit from 5-10 bucks, when you open the unit you will see the one that is bad, is usually bent or the connector might be burn or melt, good luck..!

The most likely problem is the magnetron. Check your warranty in owners manual, I believe you have five year warranty on magnetron.

Since it's under a year old, it's fully under warranty.

sounds like either a powerboard or control board is sending erratic voltage or no voltage to the table motor and possibly the light.

Generally, the most common causes of a failure to heat are:

 

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose conneciton on the control unit circuit board
- bad magnetron or other high voltage part
