Sparks coming from compressor, smells like burnt rubber

This could be the valves on the head that are not closing all the way. They can become warped from heat or debris

Burnt smell is not a good sign. If your compressor is not turning and the clixon does not shut off power you will hear a humming sound and start smelling as unit burns it self up. Chances are your compressor has seized and needs to be replaced.

You may have an accessory locking up, like your A/C compressor. Remove your serpentine and check for any binding of the accessory pulleys or a bad tensioner or idler. Also, check for a ground in the positive side of the charging system. Do you see any smoke coming from the engine when this occurs?

either way i wd. replace the assembly! ck. alll the idelers and tentioner pulleyys

Smoke from under the hood ?
Smells like burnt rubber ?
Either the compressor or the comtressor clutch is bad so it locks up wen you urn it on and the fan belt is burning..

have the ac system inspected..

the compressor is asealed unit and wont cause any smell but it does have a push on starter on the compressor pins under the cover (most likely cause)
Possible other faults are defrost element or defrost timer

Check serpentine belt, the radidator hose , the air conditioner compressor and also the differential seal they common cause for rubber smell.

Check for any rubber part that can be in contact with exhaust system and inspect wirings looking for shorts.

Also ensure that the smell is not coming from a bad tyre, and check for oil leaks in your engine, burnt oil can be confused with rubbere smell.

ok the rubber smell is your socks and underwear band,,and things with elastic in them ...ok open your dryer ,,look in the back where the hot air blows out,,,does it look like a burned iron..that where the clothe stick and melt too..just take a brillo with a little bit of water,,little dampness ans scrub the area..onthejob...

There is a seal between the compressor and the motor that in failed condition will leak oil into motor windings causing burnt oil smell. Some hitachi compressors suffered from failed valves or head gasket causing extra heat but not oil smell. These compressors also have a thermobreaker built into the windings that when failed will prevent motor from starting or would start and run for only a few moments then open. This part is not replaceable. enjoy

Are you sure the burnt smell is coming from the washer and not from the dryer? If you've placed a rubber backed rug or other similar article of clothing, it is not uncommon for that rubber backing to melt and get embedded in the heated duct of the dryer . Not sure this helps but if you can clarify the point at which the burnt smell is first observed that would help..
Thanks
