(a)

CAUTION

When replacing the heater, please be careful not to apply force, such as vacuum pipe is bent.

(b)

CAUTION

Replacing the heating element is very dangerous. Be sure to turn the power switch OFF and be careful of 

the following procedure when replacing the heating element.

B. Measure the resistance value

Normal heater resistance value

Connect an ohmmeter across the connector terminals (a). 

The correct values are approximately: 14Ω (

±10% 

100-110V), 17Ω (

±10% 

120V), 41Ω (

±10% 

220-240V).

If the resistance value is incorrect, replace the part.

Normal sensor resistance value

Connect an ohmmeter across the connector terminals (b). If the resistance value 

is ∞, replace the 

part.

Refer to the instructions included with the replacement part.

CAUTION

Handle the heating element with care. Never touch the heating element wire!
