PROBLEM PROBABLE CAUSES CORRECTIVE ACTION
Water boils in simmer
mode.
A. Failed/shorted temperature probe.
Test: Check for shorted probe
circuit. Probe resistance should be
approximately 552 Ohms @ 60°F
(16°C), 655 Ohms @ 100°F
(38°C), and 1000 Ohms @ 212°F
(100°C). See probe resistance
chart on page 1-17 for other
temperatures.
A. If resistance is out of
specification, replace the
temperature probe.
Water temperature too
low in simmer mode.
A. Controller out of calibration A. Recalibrate simmer setpoint.
B. Temperature probe open.
Test: Check for loose
connections.
B. If connections are secure, re-
place temperature probe.
