Heater Resistance Checks
NOTE:
For dispense valve and hose sensor resistance
checks, refer to your dispense valve manual or hose
manual.
To check the heater resistance:
1. Make sure the power is off and the main power
switch (MP) is in the OFF position.
2. Make electrical resistance checks for the compo-
nents. Refer to T
3. Replace any parts whose resistance readings do
not comply with the ranges listed in T
NOTE:
Check the resistance at ambient room tempera-
ture (63°– 77°F [17°– 25°C]
).
To reduce the risk of electric shock, conduct electrical
checks with the main power switch (MP) OFF.
