Samsung microwave oven model SMH1622S exhaust fan will not shut off high fan and low fan will switch but the off dose not work.


On model SMH1622S, I would first check the hood TCO. It should be normally open (infinite resistance on a continuity test). If it has shorted, then the hood vent exhaust fan will stay on.

If that's good, then it is probably a shorted vent relay on the control board, which I can repair.

Details are here, where I also have a video showing how to remove the grille and controller assembly in about 5 minutes.

If you have any trouble getting the grille off once the screws are removed, slide the hood vent grille to the left about 1/4", then then pull it forward. On some models there are L-shaped clips that fit into a slot to hold bottom of the vent.

The Fast Track repair manual for model SMH1622 is here. It will be useful.

If you have other questions, it's best to follow up with me directly.

I bought a new door handle to replace a broken one. How do I access the top screw?


Normally You have to separate the door panels (as shown in the attached photo) and then you'll see the previously hidden screw(s) you need to remove.

Or you can watch a YouTube video (not a video I made) that demonstrates how it's done.

In some cases, you then have to gently rotate the handle to unlock it.
You can find helpful exploded view diagrams and order parts by entering your full model number here.

SMH9151W--se ERROR MESSAGE-HOW TO FIX


The 5E error indicates a problem with the key pad. The microwave computer believes there is a short between the key pad and the central board. You may be able to temporarily reset the error by unplugging the microwave for at least 30 seconds. (In some cases, tripping your circuit breaker may be an easier way to disconnect the power to an over the range microwave.)

Some people have been able to solve the code by cleaning the contacts in the wiring harness. The recommended solution is to replace the assembly control panel (switch membrane, window and control panel). See http://www.searspartsdirect.com/samsung-microwave-parts/model-SMH9151WXAA0000/1482/0123370/50041332/00004.html for a parts diagram and some prices.

Since microwaves have capacitors that store significant amounts of energy, you may want a professional to take apart the microwave and do the repair.

I hope this helps.

Microwave has no power


Besides the regular fuse your microwave has two thermal fuses - one is attached to the magnetron tube (called the magnetron Thermal Cut Off or TCO) and the cavity TCO (usually located under the air ducts on the left side of the microwave). If you have the wiring diagram (usually supplied with the microwave) you can find them there. Unfortunately the model number you provided is incomplete and I'm not able to find the wiring diagram for your microwave.

Microwave shut off like it lost power but the receptacle does have power to it. My model is an LVM1750.


The thermal cut out switch in the cavity is bad. I was unable to locate a wiring diagram on the internet but when I took the microwave apart, I found the wiring diagram inside the microwave on the back side of the touch panel.

This unit is mounted above the stove. We were cooking on the stove and also in the microwave. I think there was enough heat to trip the TCO switch.

Wiring diagram Problem - Maytag MMV5207A 1100 Watts Microwave Oven


If it is the magnetron cooling fan, it should be a one-speed type.

Assuming your AC line power is correct (110-125VAC) then the fan may be bad, or there may be a problem with the relay on the control board or indeed a bad connection in the wiring.

The way I would test it is to disconnect the fan and the connect a line cord directly to it.

I've uploaded the wiring diagram to my site at:
http://207.234.249.73/mwd/mmv5000_wiring.gif

If you think it's the control board, we repair these for $39.95 in most cases.

Wiring diagram Problem - Maytag MMV5207A 1100 Watts Microwave Oven


This doesn't have the diagram hidden away somewhere inside? Check at the bottom edge of the control panel, transformer brack, or rear of the oven. Otherwise, you can find wiring diagrams of earlier models that may be close enough. Just enter your model number here: http://tinyurl.com/gv383

Power


You can download some models' owner's manuals here: http://www.samsung.com/support/productsupport/download/index.aspx But the attached diagram shows how power levels are categorized or rated. When you want to cook at a power level other than high, you normally hit POWER then a number from 1-0. On some models you press POWER repeatedly until it shows the power level you want.
