Troubleshooting Gas Control System (Af4000 Valve) - Majestic 33LDVT Installation Instructions And Homeowner's Manual

If erratic system behavior is observed that cannot be resolved by the methods outlined below, ensure that there is
not a transmitter with batteries installed that may be interfering. If a transmitter is packed with batteries installed, its
buttons may be depressed sending a constant signal which can interfere with the transmission of desired signals. A
transmitter with new batteries can have a range of over 100' (30.4 m). (Page 10, Fig. 10)

Troubleshooting
American Flame Gas Control System
•
Ensure the REMOTE/OFF switch on the side of the module (Fig. 46) is set to
OFF.
•
Make sure the leads from the AC power adapter are securely connected to the
POWER terminals on the control module and 120V AC power is available. (Fig.
47)
•
Make sure the remote wall switch is wired correctly.
•
Verify the gas supply is turned on.
•
Ensure the orange lead from the pilot assembly igniter is securely connected to
the terminal labeled "I" and the white lead from the flame rectification sensor is
securely connected to the terminal labeled "S" on the control module. (Fig. 46)
•
Make sure the orange and white leads from the module are securely connected to
the terminals labeled "PILOT" on the valve body. (Fig. 48)
•
Ensure the black GROUND wire is securely connected to an appropriate metal
portion of the valve or pilot assembly. A proper ground is essential to spark
igniter operation.
•
Make certain the pilot flame is in contact with the flame rectification sensor on the
pilot assembly. This valve is equipped with a pilot flame adjustment screw. (Fig.
48) If the pilot flame is too small it will not contact the flame rectification sensor
and will not complete the safety circuit.
•
Check continuity of pilot coil on valve. Remove wire connector. If there is no conti-
nuity on pin terminals, replace valve.
•
Ensure the CONTINUOUS PILOT switch on the control module (Fig. 46) is set to
OFF.
•
Verify the gas supply is turned on.
•
Ensure the pilot flame will ignite. If not, see pilot flame troubleshooting above.
•
Make sure the green and white leads from the module are securely connected to
the terminals labeled "MAIN: on the valve body. (Fig. 48)
•
Make certain the pilot flame is in contact with the flame rectification sensor on the
pilot assembly. This valve is equipped with a pilot flame adjustment screw. (Fig.
48) If the pilot flame is too small it will not contact the flame rectification sensor
and will not complete the safety circuit.
•
Ensure the pilot flame is properly located to ignite the main flame.
•
Check continuity of main burner coil in gas valve. Remove wire connector. If there
is no continuity, replace valve.
