Question about Estate TMH14XL Microwave Oven

1 Answer

Micro stopped working tonight

I used the micro for 10 mins on high heat. Went to heat something else and the turntable wasn't working. Looked further and no heat. Dad is suggesting to replace the Klystron or fuse. Are we better off to junk and start new?

RE: Samsung microwave SMH7187STG mfg'd 5/08. I heated cup of tea 2 min.Then I closed micro's door & micro emitted a continuous electrical buzzing sound.I opened door & buzzing stopped.


The cook relay on your control board is shorted, and the unit is cooking whenever you close the door.

When the magnetron overheats, its thermostat opens, shutting power down until the unit cools to a safe level, then power is restored.

I regularly repair these with my $54.95 service, which includes insured return shipping.

Details are here, or for full information and instructions, please e-mail me here at pupista@gmail.com and remind me of your full model number and symptoms.

Why would the turntable stop turning and the unit stop heating?


hi,
there is a micro switch that signals when the door is closed. this tells the machine that it's okay to start the turntable and heating process.. if the micro switch breaks or shorts out then the switch does not send the signal so the machine does not work.

I put my Microwave on for 30 min and it suddenly stopped working, suggestions?


If there is no power at all to the display or the panel then it is failure of the board. But if there is power without heating, if the turntable/fan/light works, then it can be related to failure of relay, Magnetron, Waveguide or capacitor.

My microwave does not heat as hot as it use to. What would cause that.


Here is a simple power test.
Place a measured cup of water into the microwave. Run the micro for 2 minutes. A 1000 watt micro will boil a cup of water in 2 min. Check the power output of your machine. It will be found on the model number tag. A 700 watt micro will take about 3 minutes. If this occurs, the machine is working properly.
Otherwise, check the outlet voltage, should be 110 or higher.
Outside of this, you could need a high voltage capacitor or magnetron.

My microwave starts however food does not heat up.


Micro wave as the name suggests produces heat when the micro waves aimed at an object causes the water molecules inside the object to vibrate hence producing heat.The gadget responsible is the magnetron. If your magnetron is not receiving ht voltage or receiving but faulty, then your micro wave wont work please take precaution when opening micro wave due to high voltage caps that remain charged sometimes even when it is off.check the high voltage fuse/ diode and capacitor if they are fine and the step up trans former o.k then the only option is to replace the magnetron

No heating, turntable does not turn, but clock & lights work.


Check to make sure the plastic on the shelve holders or tuntable guide did not wear and expose metal. If these holders or brackets are wore and exposed metal it shorted out your micro wave. They need to be replaced and a fuse needs to be replaced inside the control panel,

A microwave can be dead for many reasons.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open. Then when it cools, it closes the circuit and allows power through again.

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven.
