Common signs include irregular cycling

The 1/4" ODF external equalizer must be connected to the suction line near the sensing bulb

This ensures the modulating gas valve remains firmly closed until the solenoid applies enough magnetic force to the plunger to overcome the spring and allow gas flow

reducing the risk of voltage drops and protecting other critical system components from electrical stress

this component ensures the system adheres to factory-spec ignition sequences
