I have an electric dryer that is about 20 years old. Recently, we had to
have our washer repaired. After the repairman left, the dryer started
periodically making a ticking sound. It sounds like water dripping. The
ticks are about 1/2 second apart. Eventually it stops on its own. It may
go into one of these spells two or three times per day for an hour or
two per spell.
The only thing I could think of that would cause this problem was the
mechanical timer, but no movement of the dial (or anything else on the
dryer) will stop the ticking. As far as I know, all the repairman did
was move the dryer to get to the washer better.
I cannot hear the spot where the ticking is coming from. How can I
diagnose this problem? It is really annoying after a while.
