    I am having the same problem with a new Tappan TMV151F and can't get anyone to come and fix it. The Lowe's store won't take it back.

    My TMV151F Tappan has an error -SE- and will not run, I have tried unplgging it and plugging back in to try and reset it, but no luck. Has anyone else had this problem or knows what this -SE- code means.

The magnetron is overheating and causing the magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

This is usually caused when the internal cooling fan is not running or by a magnetron that is failing.

When I say internal cooling fan, I do not mean the hood vent exhaust fan which you can turn on and off manually.

I'm instead talking about the internal fan which comes on automatically whenever you microwave.

It is vital that the cooling fan runs, or the magnetron will be
destroyed.


It may also be a clogged exhaust duct or filter. Grease filters should be cleaned regularly and charcoal filters should be replaced (not cleaned) every 6-12 months.

You can refer to your owner;s manual for that info.

You can download most Maytag / Whirlpool / Tappan owner's manuals and installation instructions here.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

I had the message -SE- showing up on my TMV151F. I opened up the control panel and made sure all the connectors were secure. I noticed the red connector was not in all the way. I also noticed that the grounding wire behind the mini-manual was touching the back part of the board so I separated it. Not sure if either of these actions fixed it or if by some miracle it fixed itself. It is working fine now.

Need help, trying to repair my Tappan Model TMV151F microwave.


That really sounds strange... It may be a door switch or a relay on the controller. (Internal contacts, not solder joints).

The service manual is here.

Did you take apart the bottom door switch to check it? Blurry but useful video here.

Under the circumstances, I would be most concerned with the bottom switch, but it wouldn't hurt to check the top one. It will not be the middle switch.

Makes a really loud buzzing noise during operation


Unit uses a Magnetron and likely a power board called an inverter to run it. Someone would have to open the unit in a way where they might pinpoint where the sound is coming from and then take action--does not of course sound normal or good to me.

I put pizza wrapped in aluminum foil into the microwave for 3-5 seconds until i saw sparks.. i took it out and it left black marks on the microwave. How do i get it off? Does the microwave still work?


If you shut it down quick enough the microwave will be operational, to remove the black marks mix baking soda in water and until becomes a paste, apply over affected area's let it sit for 5 minutes and wipe off with clean warm water.

My TAPPAN Microwave Oven Model Type: TM5430 B only shows S1 in the display and it doesen't react if i push any othetr buttons. What can i do ???


Unplug the unit, let it sit for a minute to clear power from the control board then plug it back in. If the display still shows S1, that could indicate a bad touch switch on the front panel, a bad connection between the touch panel and the control or a failure in the control. Unless you can get parts cheap and fix it your self, it's not worth paying for the repair.

Tappan TMV151FS over range microwave starts to work and then dies


Never run the microwave without a load (something to heat)!!! That kills the microwave generating parts.

Sounds like a 'thermal' protect switch is activating after running. Make sure that (if the unit is mounted in a cabinet) that there is sufficient space around the unit for proper air flow and that nothing is blocking the vents. Try setting it on a counter top and heat something. If it works properly and doesn't shut off, the venting space is the problem. You may have to have the cabinet that it sits in redesigned for more clearance.
