Solenoid Valve - Dometic S1521 Service Tips Manual

THERMISTOR ADJUSTER
Do an ohms resistance check across the terminals. Proper ohms reading is approximately 23,200 ohms
± 10%.

SOLENOID VALVE

Check the solenoid with a properly calibrated ohm meter. Remove the connector from the solenoid and
measure the resistance across the terminals. The proper reading would be 49 ohms with tolerance
range of ten percent.
Next, hook up a manometer at the test port. Then check for DC volts at gas valve terminals while the
unit is in trial-for-ignition. If DC volts are present and pressure is low, replace the valve. If DC volts are
not present at the valve while the unit is in trial-for ignition, verify that the wire at Plug 3, Terminal 2 on
lower circuit board has DC volts (9 or more).
