20 Most Recent Tappan TMT157E1 Microwave Oven Questions & Answers

please follow this steps and fix it. God bless youLine FuseEvery microwave oven has a line fuse. This fuse is designed to blow if too much current is drawn through the microwave circuitry. The fuse can be replaced, but the underlying issue should still be investigated and resolved. Otherwise the new fuse will blow also.Main Control BoardIf the microwave is not working the main control board may be defective. This is not common. When a microwave stops working the problem is usually the line fuse or within the high voltage circuit; either the high voltage capacitor, diode, transformer or magnetron.Thermal FuseIf the microwave is not working the thermal fuse may have blown. It can be tested for continuity. Watch our fuse testing video for more information.ThermoprotectorIf the microwave is not working the thermoprotector may have tripped. This is a safety device to prevent the microwave from overheating. It can be tested for continuity to see if it's blown.

Was the potato wrapped in tinfoil when you were cooking it?

Check fuses that are more than one inside the cabinet

open the door and on the inside it will tell you what wattage it is

Microwaves do normally 'turn on', in that the light comes on and the fan starts running. If the turntable starts turning and it is emitting microwave energy, then you need to take it for service or replace it. To me, it sounds fine.

You might have better luck on ebay.

The fuse is inside the cabinet.

Try typing the product information into the search engine of your computer, and a dealer should show up. Or, type your model number into the proper box on the website "Searspartsdirect" and they should show you your glass tray on a schematic. You can buy from them, or on Amazon, or on e-bay, God bless your efforts,

Hello, Sarkis - I found 4 descriptions of what may be causing the noise when you operate your microwave oven. See the information on all 4 possible causes here: https://www.repairclinic.com/RepairHelp/How-To-Fix-A-Microwave/78-88--/Tappan-Microwave-is-loud-or-noisy Note: Safety advice I have read regarding microwave oven repair is to have a microwave oven repaired only by an authorized repair technician. It is not do-it-yourself work. Any repair might not be worth the cost compared to purchasing a new replacement. A microwave repair technician authorized to work on Tappan microwave ovens will be able to evaluate what is causing the loud noise and give you an estimate of the repair costs. Note: If you find you need to replace your microwave oven, please be sure the old microwave oven is sent to electronics recycling. Best wishes.

I had very old parts for the tappan units but they have been out of circulation for quite some time. Unless this is a new tappan that I am not familar with, Most of those parts are no longer available. The FCC ID does not help, you need a model number of the unit to try to look up parts. A Microwave puts out radio waves and such has to be regulated by the FCC. Federal Comunications Commission. That number wont help find parts for the unit. Sorry

Hey Twiddledum.... .. NEVER post this much info on line... the entire world can see it..(even bad people).. Sounds like this unit has served you well... price a new one...

I would first check the door switches and mounts. My door switch help file is here. If those are good, then you likely have a shorted relay on the control boar, which I can repair for you. Details are here. FixYa doesn't notify us when there's a response, so if you have other questions, please contact me directly. - William E.

is there no user manual on online how old is the microwave good thing is you can still get parts http://www.searspartsdirect.com/model-number/5694311005/1269/0123245.html

Before considering a control panel replacement, check all door switches to make sure they are making contact in both directions (some may be single pole double throw). If you need further help, I’m available over the phone at https://www.6ya.com/expert/david_29ad5d1dd86564b0

I gues you are misintepreting something. Maybe wattage for 110V or 220W? Take a photo and post it wth your question

Have a look at the info panel... 1 Watt is a Volt Amp.

There are several switches (usually 3) located and attached to the door latch area of the microwave. One is a safety interlock that keeps the Micro from running with the door open. At first one of the switches were sticking slightly giving you the attempted run. Then enough stuck to cause the safety to sense it. The safety usually will blow the internal fuse or house breaker. If you are going to get it fixed, best to replace all the door switches and then the fuse also. If by chance it still blows the fuse again you have other problems. At this point I think its just the door switches and fuse.

Unless there is moisture or grease on the control circuit board, "SE" error means you have a shorted membrane keypad. The solution is actually a pretty simple DIY job - to replace the control panel frame assembly - which comes with a new keypad already installed. If I had your full model number from the tag on the oven I could likely give you step by step instructions with the part number you need. You can find links to helpful exploded view diagrams and part ordering help here, where you can also e-mail me directly. I recommend that you bookmark that link to your favorites.

Then you have blown a fuse. Check inside the oven chamber and look for missing powder paint or signs of arcing, if so dispose of the microwave. If the inside is good remove all the screws and remove the cover. Replace the fuse. If the magnetron was making louder noises prior then replace the magnetron. Since the fuse went the giant capacitor is likely bad. While the cabinet is open make sure to look for burned wires, check the continuity of thermal cutoffs, and check the main circuit-board for burned traces or components. The relays in most electronics are known for arcing (spot welding) and staying in the wrong position. Tap them hard with the back end of a screwdriver. During all of this use safe electrical practices by having the power cord unplugged. The capacitor could still have a high charge on it so be careful.
