Checking Crankcase Heater Thermostat; Compressor Sound Cover - Lennox XP25-024-230-01 Installation And Service Procedure

Crankcase Heater Thermostat: As the detected temperature changes the resistance across the sensor changes. Table 18
on page 78 shows how the resistance varies as the temperature changes for this sensor.
NOTE - When checking the ohms across a sensor, be aware that a sensor showing a resistance value that is not within the
range shown in table 18 on page 78, may be performing as designed. However, if a shorted or open circuit is detected, the
sensor is faulty; the sensor needs to be replaced.
