High-Limit Thermostats
Location / Function / Testing
During all Modes...
Line voltage continually ows thru the normally closed contacts of the two
high-limit thermostats. is circuit powers all of the line voltage components,
except for the fan system.
If the temperature at either of the thermostats exceeds 450°F (+/- 25°) / 232°C
(+/- 14°), the thermostat contacts open. is interrupts power, and terminates
the cycle. [An error code will appear on the display].
e thermostat contacts reset to the closed position at approximately 325°F /
163°C.
Note: Thermostats must be tested at room temperature.
