Burning plastic smell from washer dryer combo

Updated: had rubber, it's actually more of a plastic smell. I have a 3 year old LG WM3987HW and two days ago it started to smell like burning plastic while it was on the drying cycle. Ran it again yesterday and it smelled like burning rubber near the beginning of the wash cycle. It didn't smell in the drum, the outlet wasn't smoking/smelling either and the wire wasn't even warm. Any idea of what could be wrong with it?

    Sorry, my boyfriend says its more of a burning plastic smell. We called a repairman who lied and said he smelt the burning plastic smell the instant he walked into our house (we haven't run the washer in two weeks) and that the burning smell is normal. If it were brand new i'd believe that but since it's basically 3 years old and it had never smelt like burning plastic until now, i highly doubt this smell is "normal".

    when he opened it up, my boyfriend believed the smell came from a black box inside the machine. The "repairman" refused to open up the part since he didn't see any burn marks on it. There are no burn marks because we stopped the machine and unplugged it the instant we smelt it.

    The box is your main board electronics has no rubber that will burn epoxy coated board may smell like formaldehyde only rubber in washer is front boot seal if bearings of inner tub are going out it will rub on seal causing the smell
    if it was the board washer would stop working take top off washer and run it and watch for smoke or smell for it you will find the area of were its coming from

    i'm sorry i misspoke on the original post, it's more of a burning plastic smell. The piece my boyfriend thought the scent came from (that the repairman wouldn't open) appears to be the black enclosure that is part of the dryer component. We had it running with the top off, saw no smoke but the entire house smelt like burnt plastic which the repairman said was "normal". It can't be normal if it only started up after 3 years of use with no "plasticky" smell after the first few times we ran it.

SOURCE: LG TROMM - awful smell while washer is running

Use the aafesh tablets as instructed, this will clear hoses that have developed some mold, also inspect drain at the wall, these get moldy and as machine runs, smell comes out of there as well.

SOURCE: LG washer, rubber burning smell

Did you get this seal problem resolved, by yourself or did you call in a repair-person? If you did it yourself, was it difficult? Same problem found 12/17/10 - Thank you

SOURCE: LG WM2487*M Washer smells like burning rubber in spin cycle

Smells like, I mean sounds like, a belt is burning either from friction caused by a bad bearing, or, a loose belt is slipping on the pully a bit, causing it to heat up from the friction.

After wash yesterday i opened door and smoke and smell of rubber burning and small amounts of grey rubber in washer

check the inside stainless steel drum isnt moving up and down. use the plastic outer drum as a reference. If its wobbling up and down, then your drum is bad. If it isnt then for some reason, the boot is making contact the drum. I would actually get a tech out to confirm this.

Few months old WM3987HW won't turn on - seems dead, unplugging and replugging won't work; outlet has power

Hi Rick,

I found your answer to another person's problem with the LG washer/dryer not turning on. We have the same problem. My husband found a piece of plastic near one set of the fuses that looks warped - like it got too hot. Is there any advice you can give? It's a piece next to the box by the main power cord with a metal coil.

I can't turn on SpinSense on my LG WM3987HW combo washer-dryer. I've tried pressing the button for 3 seconds in nearly every mode, on or off, locked, unlocked, wash, spin, rinse. I've managed to get it on...

I have an earlier version of your machine (WM3988HWA). What I've found is that you can't use the Spinsense feature if you've got the Dry cycle set to go after your wash. I have no idea why they designed it this way!
We run the wash first without setting it to dry, and have no problem turning Spinsense on. I usually hold it down for 3 second after hitting the start button, but you can also do it before you start the wash. When the wash is done, then we start a dry cycle.
This is the main flaw with our otherwise great machine. I posted about it at http://www.fixya.com/ThreadAsker.aspx?thid=1844295 a long time ago but never got any advice.

Can you buy a frigidaire stackable washer separately?

Have you had a qualified service man look at your machine? I would think that the burned rubber smell would direct you to examine the belt (found in the very bottom after removal of front cover).
If it is the belt it is a very easy fix on this machine. The not draining part wouldn't be related to the belt the pump that does the draining is driven by its own electric motor and is easily visible when the front cover is off. Its located on the bottom left side. If a sock or other small item manages to get over the side of the basket it always ends up jamming the pump.
You would have to take the pump apart to retrieve the item and restore pump function
Good Luck
