TEMPERATURE SOLENOID
The temperature solenoid may become seized due
to hard water deposits. Make certain that the core
moves freely in the stem. Also, the plunger must
move freely within the guide. Clean with #0000 steel
wool.
Check the seat to make sure that it is not distorted.
Clean the seat, using a 3/64” drill bit. ROTATE THE
DRILL BIT WITH YOUR FINGERS ONLY.
NOTE: DO NOT over-tighten nut when re-
assembling temperature solenoid. Over-
tightening the nut will damage the coil.
