Smoke and burning plastic smell in microwave oven


Burning plastic, not food? A component has overheated badly then, with a plastic case. The main suspect would be the high voltage capacitor in the magnetron supply. This is cheap and easily replaced ONLY IF you know what you are doing and can diagnose the fault. If you don't then DO NOT take the case off the unit as fatal voltages can be present inside even if the unit is unplugged.

I'd just buy another, as they are generally uneconomical to have repaired by a service tech.

I wish to STRONGLY reinforce the intent of what krbjump was saying in terms of...


Well, those of you who have no idea why a Screen Voltage (technically known as G2) adjustment may interest you, here is a photo of a bad adjustment (too high).

8914ffc.jpg

You may also experience smeared colors… this is caused by a low adjustment. To correct this, we need to get the back off of the TV. It would be a good time to unplug it if you have not already done so. Next we locate the FBT (Fly-Back Transformer).

be30da0.jpg

This is a 20” model and it has 2 knobs. Your FBT may vary, as some slim designs and some large tube models may have 3 knobs.

You will need to look closely at the knobs; they will be labeled “Focus” or “Screen”. On units with 3 knobs, there will be 2 focus knobs and 1 screen. For now, we will be working with at the Screen knob only.

0007e62.jpg
d784a76.jpg
With the adjustments identified, we are ready to plug the TV in (including your standard cable connection) and turn it on… BECARFUL!!! For the rest of this adjustment, we will be working inside of an electrically charged TV. We also need to normalize the picture, so go into your TV menu and adjust the Picture and Brightness settings to the middle or center.

If your TV normally displays a black screen when you do not have a signal connected, ex: Video input 1, then this will be the quickest and easiest setup for you to use. However, if you are not so lucky, you may need to bust through your DVD video collection and find a “between scenes” shot that you can pause on to give you as black of a picture as possible. Eliminate as much light in the room as you can (just remember, you still need to see what your doing)… we want a good view of the screen without the interference of ambient lighting.

Once you have your black screen all set, we are now ready to proceed to the adjustment. If you have lines on the screen, see (HIGH)… if you have color smear, see (LOW).

HIGH: If you have some lines in the picture with a washed out appearance, your Screen voltage is too high. You will need to turn the Screen knob on the FBT counter-clockwise. Do this slowly, until the lines are no longer visible. If you still have a small amount of illumination coming from the screen, back it down a touch further until this just disappears.

LOW: If you have smeared colors in the picture that seem to trail of the edges, your Screen voltage is too low. You will need to turn the Screen knob on the FBT clockwise. Do this slowly, until you just see some lines zigzagging top to bottom on the screen. Now, you will need to turn the Screen knob on the FBT counter-clockwise. Do this slowly, until the lines are no longer visible. If you still have a small amount of illumination coming from the screen, back it down a touch further until this just disappears.

The final set, switch the TV input over to your cable input and check out the picture. Take a good look at some bright scenes and dark scenes. Do they look ok? Adjust the Picture and Brightness in your menu… can you set the picture to your liking? If so, you are all set. If not, double check your work (remember to normalize the Picture and Brightness setting).

feab016.jpg

If you are unable to adjust the Screen voltage as described above, you may have a High Voltage problem with your TV. This will require a repair and is not covered by this tutorial.

If you are all set and the adjustment is good, we should have a quick look at the focus adjustment. Return the TV to your Black screen setup. Press the TV menu button to give you nice fixed display to focus. Adjust the focus knob(s) until you have the clearest picture. It’s important to balance the center of the picture with the corners of the picture. If the center is too sharp and the edges and corners are blurry, it is not a good adjustment. Do your best, you are the final judge of your work here.

35fa2ea.jpg

Once you have finished the adjustments and verified the picture with your cable picture, you are ready to close it up and return the TV to normal service. Unplug the TV, replace the back cover… enjoy!

I hope this was helpful. If you benefit from this tutorial, please leave some feedback.

Maytag atlantis series mav6200aww, there was a burning rubbery smell today when it was in the spin cycle. I turned it off and unplugged it what could it be


could be a belt and or the pulleys under the machine are plastic so one of them could have melted along with the belt smoking. could be something in pump or look in washer and see if there mite be a nail or something like a nail in one of the little holes in the inner tub . the nail could be making the machine not spin and could be causing the belt also to smoke.

The computer board is melting strong smell of burning plastic


Hello,

Welcome to FixYa.
Based on your description ( specifically the smell ) I would suspect the control board is faulty.

However, these faults are usually easy to identify and again based on the fact that none of the indicators are working I`d rule those both out quite quickly.

The control board for those is not that expensive, relative to the cost of the machine at least... typically around $250. The original Asko part is, 8801286.

I would be one of a minority I think in saying these are great dishwashers, but typically they are doomed from day one due to improper installation and improper service by unqualified techs & "handymen".

If you decide to try to inspect or repair just remember please...

**Turn off the power at your main breaker before attempting any service...safety first**

Let me know if I can assist you further. Thank you for choosing FixYa today.

Please take a second to accept and rate the info I provided for you here today.

Good luck.

The unit works as of right now...but there is a smell of something burning


Quite often, if you smell like a plastic burning smell, one of the capacitors is faulty, and should be checked immediately. Quite often the compressor start capacitor, will get hot and start to melt. Have it checked by qualified technician or electrician, as they are dangerous and can give a fatal shock if not experienced with handling them, even when power is shut off. $20-$30 part, and 1/2hr. labor should take care of it. The cover on roof unit, has to be removed to access the capacitors, so watch for bees, wasps, when you do so. Make sure power is off at breaker panel.

Maytag Neptune Dryer with strong "burned electrical wiring" smell


Sounds like the motor went out. Before trying to start it it needs to be inspected. If you are not comfortable opening up the cabinet then I would would recommend calling a service tech. If you need further assistance please let me know.

Strong ''burning plastic'' type smell coming through heating ducts.


it sounds like you have a main air movement system motor that is burning out. it will probably quit on you in the next few days. likely cost to repair from company 375-700 somtimes more if you have a variable speed furnace, in which case you should consider replacing the whole furnace for what it would cost for the motor on one of those.

on board fuse probably burned. and flash probably dead now.
need to send this to canon. they have fixed price major and fixed price minor service rates. not very expensive. on the other hand, you might invest in a newer camera or an upgrade.
