TESTING SOLENOID

WARNING

Do not attempt service on the solenoid without

first disconnecting the electrical power at the

main power source.

1. Remove the screws securing the draft enclosure

cover; then remove the cover.

CAUTION

Solenoid may be hot.

2. Carefully disconnect the two wire leads connected

to the left side of the solenoid by gently pulling and

moving them from side to side.

3. Using a multimeter set to Ohms, test the solenoid's

resistance by touching the meter leads to the solenoid

terminals.

4. If the multimeter reading is between 15 and 30 Ohms,

the solenoid is good. If the multimeter reading is less

than 15 Ohms or more the 30 Ohms, the solenoid is

faulty and should be replaced.

5. If the solenoid is good, carefully attach the wire leads

onto the solenoid terminals (white wire connected to

the upper terminal).

6. Install the cover and secure with the screws.

7. Turn the Power Disconnect Switch to the ON

position.

REPLACING SOLENOID

WARNING

Do not attempt service on the solenoid without

first disconnecting the electrical power at the

main power source.

1. Remove the screws securing the draft enclosure

cover; then remove the cover.

CAUTION

Solenoid may be hot.

2. Carefully disconnect the two wire leads connected

to the left side of the solenoid by gently pulling and

moving them from side to side.

3. Remove the top cotter key of the linkage.

4. While supporting the solenoid with your hand,

remove the top two solenoid mounting screws and

loosen the bottom two.

5. Lift up on the solenoid until it clears the screw heads

and remove.

6. Place the new solenoid into position and lightly

secure with the screws. Adjust the solenoid up

or down until the solenoid plunger free length is

between 15/16" and 1"; then tighten the screws

securely. Connect the solenoid to the linkage with

the cotter pin. Slightly spread the legs of the cotter

pin. Check that the spring-loaded linkage and

damper door are not binding and that the spring is

not broken or missing.

7. Carefully attach the wire leads onto the solenoid

terminals (white wire connected to the upper

terminal).

8. Install the cover and secure with the screws.

9. Turn the Power Disconnect Switch to the ON

position.

NOTE: If the solenoid rattles during operation,

the alignment between the solenoid and the lift

tab is incorrect. To align the solenoid and lift tab,

loosen the four solenoid mounting screws and

move the solenoid until the solenoid plunger

aligns with the lift tab. Secure the solenoid; then

make sure it operates smoothly.
