Checking the Temperature Sensors
Introduction
If the cause of the problem is related to the temperature sensors, then the sensors should be checked
prior to changing the PCB or an output device.
Types of sensors
There are two types of temperature sensors:
■
sensors connected to the controller PCB: R3T/ R4T/ R5T/R6T
■
sensors connected to the defrost PCB: R11T/ R12T/ R21T/ R22T/ R31T/ R32T
How to check
To check the temperature sensors, proceed as follows:
Table 1
In table 1 you will find the temperature-resistance values of the controller sensors R3T, R4T R5T and
R6T (see next page).
Table 2
In table 2 you will find the temperature-resistance values of the defrost sensors R11T, R12T, R21T,
R22T, R31T and R32T(see page 3-16).
Step
Action
1
Disconnect the sensor from the PCB.
2
Measure the temperature and the resistor value.
3
Check if the measured values correspond with the values in the appropriate table.
