I have a stacked Maytag S1000 washer and dryer with an SG1000 (Gas)
dryer part. All touch-panel electronic controls. Both the washer and
dryer parts operate well.
The dryer dries the clothes, drum turns properly, adequate heat and
air flow, all cycles perform as expected but there's a weird noise
from the dryer. I can't reproduce it. Happens without any obvious
outside interference such as large loads or lots of use that day of
the machine and it's not necessarily the first load of the day. It
always occurs after the machine has been running for some time
although not after any consistent time and doesn't seem to interfere
with the normal operation.
It sounds like the buzzer you hear when someone lets you in to a
restricted area like the door to a jewelry store, or the door that
lets you into the office part of a store, or into a doctor's office.
Bzzzz... Lasts about a minute, maybe even less, and at the end there's
a "ker...chunk" or "ker...click" and the buzzing ceases.
Without wanting to prejudice anyone's suggested diagnosis, my guess is
that it's a relay which is not making proper contact (the buzzing is
the spark jumping the gap) but finally after building up enough
current (?) it finally clicks in (the ker...click). The problem with
this idea is that there's no consequence to the click. The machine
doesn't stop or noticeably change anything. There is a thing shown in
the manual called a "drive motor run relay" but this seems to be the
relay to start and run the dryer. If it didn't click in when called
upon to do so it would be at the beginning before the drum started to
turn. There's also a "heater relay" which seems to turn on and off the
heat but if this is defective it too should also be at the beginning
(maybe later on as well). If the dryer wasn't electronic I'd suspect
the timer rotor but it is so this can't be the problem.
Does anyone have any suggestions?
I'll bet it's end-of-cycle signal circuit failure. I've seen it
times on the S1000's, making several different sounds. One I
remember was making a low noise 24/7 whether the dryer was
running or not. Really irritating.
I'd disconnect the little piezo electric speaker from the pcboard
to diagnoise this. It just unplugs, and that'll tell you whether
coming from the electronics, or somewhere else.
Just remove the two screws that hold the chrome control frame,
then 3 that hold the pcboard, and swing it forward to access the
You'll see the speaker mounted to the right of the board. Follow
its wires, unplug it from the board, and try it again. On some of
these, you can unplug the speaker without removing the board.
If that's the source of the noise, I recommend just leaving it
disconnected. The boards are really expensive, if you can find
one. I have one customer whose SE1000's speaker I disconn'd
like this about 20 years ago, and it's been working fine ever
Hope that's of some help.
