Question about Frigidaire FMV145K Microwave Oven

Open Question

Hi Expert, I have a frigidaire fmv145bc1 microwave. It seems to be frozen in a functions. Symptom: start cooking food, I interrupt the cooking by opening the door or pressing stop. I close the door and the led tells me to "press start" to continue cooking. Now all buttons will not work except for clock button interupts the "press start" message but as soon as you release the clock button the "start message comes back. Also the fan, light, and delay start work but delay will not start as I can not get the start button to work. I unplug the microwave and all is good until I interupt the function again. Any Ideas from my discription what part of the circuit board need repair??? Thanks for you help, George

SOURCE: frigidaire won't run

Quite often this is due to a bad door switch. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk

SOURCE: Microwave Buttons Not Working

The cycling of your electricity probably didn't hurt it.

Chances are moisture or grease has gotten into the controls. That can ruin the keypad.

The way to prevent that is to be sure you have the microwave's hood vent exhaust fan running whenever you are cooking on the stove top.

If you (or someone you know) might want to replace the keypad yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

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.

If you would like to have us do this for you, we do that for $39.95 plus part costs.

Please feel free to contact me directly if you need more help.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

SOURCE: Microwave Oven Does Not Start Cooking

This is usually caused by either a bad door switch or a loose door switch mount, which are pretty simple problems to fix.

Even though a door switch clicks, it may still be bad inside.

Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

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

You can 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.

If you don't find yours, or if you want to look at it without disassembling the oven, you can download it here.

If yours is not shown at the parts site or manual site linked above, Please reply back with your brand and model number so we can help you.

If you only need a switch, you can order a universal type here for $5 postpaid.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases in about a week or so.

Not heating


Hello


Power Supply

Check whether there is a proper power supply. Look to see whether the cord is connected to a grounded 3-prong outlet and the cord is fully plugged in. If the electrical system is built-in and no power cord is visible, replace or reset the household fuse or circuit breaker.

Microwave Functions

Some basic microwave operational steps may affect whether the microwave is heating. Open and close the microwave door, as the unit will not function with the door open, and push "Stop/Clear" to cancel any previous settings, such as the timer, which do not heat the microwave oven.

Setting the Microwave

Once the power to the microwave has been reset, or verified as working, and the microwave is ready to run, select a new cook cycle and press "Start" to see if the microwave begins to run and cook food as expected. Allow the food to cook for the alloted time and then open the microwave door and check to see if the food has cooked or heated. Choose a longer cooking time and restart the microwave if food is heating but is cooking slowly.

Repair

If all efforts to troubleshoot the function and power to the microwave still do not get the appliance heating food as expected, there may be a repair issue that needs to be addressed. Contact professional technician for advice.

Frigidaire PLMV168K2 micro wave stopped heating food. Still has turntable and light functions. Seems to have more of a power load after initial start. The buzz is more intense than normal.


A loud buzz is a symptom of a shorted magnetron or high voltage diode. Would recommend that you take it to a qualified repair facility if you want it repaired, but if the magnetron has failed, the part costs can equal that of a new oven.

Frigidaire microwave doesn't work


Don't have a fix for your problem, but my Frigidaire microhood just did the exact same thing--about the same age, started cooking some food and it worked for a few minutes and then just stopped--time kept going, light stayed on, but turn table stopped and fan noise cut out. I tried it a few more times and it seemed to fade in and out and then stopped trying.
