Testing Procedures

!WARNING

To avoid risk of electrical shock, personal injury or death; disconnect power and gas to oven before servicing, unless testing requires power and/or gas.

Component	Test Procedure	Results
Electronic	F1−1 –Upper Oven >650°F with door unlocked	Check actual upper oven temperature,
range control	F1−2 –Lower Oven >650°F with door unlocked	if > 650°F check sensor.
		Check actual lower oven temperature,
	F1−3 –Upper Oven >950°F with door locked	if > 650°F check sensor.
		Check actual upper oven temperature,
	F1−4 –Lower Oven >950°F with door locked	if > 950°F check sensor.
		Check actual lower oven temperature,
	F1−7 –Membrane switch is not responding	if > 950°F check sensor.
		Check membrane switch for connection or damage.
	F3−1 –Upper sensor is shorted at (< 100 Ω) or
	open at (>5 K Ω)	Check upper sensor, harness, and connections
	F3−2 –Lower sensor is shorted at (< 100 Ω) or	Check upper sensor, harness, and connections
	open at (>5 K Ω)
