There are a lot of folks who've had power supply issues with this sub. Typically, the large resistors fail, which takes out the capacitors.

If you know how to read schematics and replace parts, then these might be helpful to you:

Here are the two pages of schematics from KLH. I wrote to their techdepartment and explicitly asked for permission to share them here.

Here's the lower board, which has the power supply:

radios often have components that over heat and burn out. Once burned out they have to be repaired or replaced. Ford F150 trucks are notorious for that.

Check the fan on broken blades - even a small part missing can cause unusual sounds. If parts are new / serviced - smell can be due to labels getting hot and emitting slight burning smell. Classic are exhaust pipes with partnumber labels left on there. If he smell stays, something in the interior might come from a crash car which was partly burned.

Maytag washer sounds like a jackhammer when rinsing - this is a new thing with all loads. Yesterday it shut down mid cycle while still full of water and we smelled a burning rubber smell. Any ideas?


There is only one belt on the machine (the burning rubber smell, probably). Sounds like something is wrong with the clutch /drive mechanism. Unless your an accomplished DIY'er, it sounds like a job for the Maytag Man.
Sorry.........................

Winding sound, with a smell of burning


I recommend to stop the use of the dryer immediately and call an expert repairman to your home. The smell of burning can only mean bad things, so better safe than sorry.
