I had an old appliance which developed bad contacts on the
mechanical time switch for the defrost cycle. For a while it was
fixable, but eventually needed replacement.

It had a secondary related problem in that the drain tube (which,
as seems usual, ran to a plastic tray on top of the compressor)
had become blocked, so the melted ice was not draining away.

This leads to another caution - if you have had to do a serious
manual defrost, the amount of water liberated will most likely be
more than the catch tray can hold, so will probably overflow onto
your flooring.
