a.Using a 1/4 in. nut driver, remove the single screw securing the igniter bracket to the burner box and carefully withdraw the igniter through the bottom of the burner box without striking the igniter on surrounding parts.

b.Inspect igniter for signs of damage or failure.

!CAUTION

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.

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.

!CAUTION

BURN HAZARD

Failure to follow this caution may result in personal injury.

Allow igniter to cool before removal. Normal operating temperatures exceed 2000°F (1093°C).

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.

!WARNING

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury or death.

Igniter wires must be securely placed in slot in manifold grommet or else they could become pinched or severed and electrically shorted.
