Whirlpool 4322452 manual Testing AN Oven Temperature Sensor

TESTING AN OVEN TEMPERATURE SENSOR

Some oven controls use an oven temperature sensor (see Figure 6-5) to operate the bake, broil, and self-clean functions. The oven temperature sensor is a “Resistance Temperature Detector (RTD)” and is composed of a stainless steel tube with a thin film of platinum on the end. The sensor is usually located inside the oven cavity at one of the upper rear corners. The RTD is nonadjustable, but it may be checked with an ohmmeter at various temperatures. To test a switch:

1.Turn off the gas and electrical power to the range.

2.Unplug the connector from the oven temperature sensor.

3.Set the ohmmeter to the R x 10 position.

4.Touch the meter leads to the plug pins. The meter should indicate approximately 1100 Ω at 75 ˚F. For resistances at other temperatures, refer to the chart below. NOTE: The readings are approximate.

	Temperature (˚F)	Resistance (Ω)
	32	1000
	75	1100
	250	1450
	350	1650
	450	1850
	550	2050
Oven Temperature	650	2230
	900	2700
