TROUBLESHOOTING GUIDE
Problem Cause Solution
Cables stay cold;
pipe does not
thaw.
No power Plug unit into 120 volt, 20 amp AC outlet. (CHS-300 requires a 120 volt, 15 amp
AC outlet.)
Reset breaker on unit.
Check if thermal protector has tripped.
Poor connection to pipe Clean pipes and clamps to ensure a good connection.
Circuit not complete Check to make sure both clamps are on the same pipe.
Check to make sure there is no plastic pipe in the line.
Check for a rubber coupling in the line.
Check to see if ice has pushed pipe connections apart.
Cables get warm;
pipe does not
thaw.
Poor connection to pipe. Clean pipes and clamps to ensure a good connection.
Check to make sure clamp is on pipe, not curb cover.
Undersize cables Use shortest cables possible. Longer length cables must be heavier gauge wire.
Long or undersize extension cord used. Use either no extension cord or appropriate heavy duty cord.
Cables get hot;
pipe does not
thaw.
No water pressure in pipe. There must be water pressure to thaw the ice. Open a faucet so the water can
flow as it melts.
Check to see if the source of water pressure is not frozen.
Check to see if the source water pump is operating.
Clamps improperly placed Check to make sure the clamps cover the frozen area.
Circuit bypassing through another pipe. Check to make sure the circuit does not go more than one way from clamp to
clamp.
