4. Check igniter resistance. Igniter resistance is affected by
temperature. Only check resistance when the igniter is at
room temperature.
a. Using an ohm meter, check resistance across both
igniter leads in connector.
b. Cold reading should be between 40 ohms and 70 ohms.
5. Remove igniter.
BURN HAZARD
Failure to follow this caution may result in personal injury.
Allow igniter to cool before removal. Normal operating
temperatures exceed 2000
°

box without striking the igniter on surrounding parts.
b. Inspect igniter for signs of damage or failure.
UNIT DAMAGE HAZARD
Failure to follow this caution may result in premature failure
of the igniter.
The igniter is fragile. DO NOT allow it to hit the side of the
burner box opening while removing or replacing it.
CAUTION
!
c. If replacement is required, replace igniter on igniter
bracket and then install assembly into burner box to
avoid damage to the igniter.
6. To replace igniter and bracket assembly, reverse items 5a
and 5b.
7. Reconnect igniter wire connection.
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury
