Checking a surge absorber (SA1)
Observation
Unplug an intended connector from
burner controller
Operate the heater
Take out the burner controller, and point the lead head at solder part of SA1
Figure 4
Turn on the multimeter and set AC
voltage range (partially direct current
range)
Insert the lead head of multimeter to
connector [lead wire side] and
measure resistance
Insert the lead head of multimeter to
connector and measure voltage
Mesuring voltage
Be careful not to insert the lead head of resistor strongly since damage in
connector may occur
