D. Mercury Contactor Replacement
Early PS200-series electric ovens and all PS310/360-se-
ries electric ovens use mercury contactors to activate the
heating elements. Each pole in the contactor is a separate
mercury-filled tube that is individually replaceable. This
feature ensures that the entire contactor should never have
to be replaced.
Individual part numbers for the mercury contactor compo-
nents are listed in the Part Number Reference sections on
Pages 140 and 142, respectively.

Then, remove the terminal clamps from the
contactor tube(s) to be replaced.

Locate the Tinnerman clips on the bottom side of
the contactor that hold each individual contact tube
in place.
Find the break in the tube bracket located in the
center. Then, using a diagonal cutter, cut the
Tinnerman clip so that it may be removed.
Remove the contact tube. If the coil must be re-
placed, all three contactor tubes must first be re-
moved.
To replace the contactor tube(s), slide the thin end
of the tube into the contactor bracket.
