## Discrepancy

COMPLAINT OF OVERHEAT AND SHUT DOWN OF HEATER DURING GROUND OPERATION.  INVESTIGATION OF HEATER OPERATION SHOWED HEATER NOT SHUTTING DOWN WITH TEMP CONTROL SWITCH.  FOUND FUEL SOLENOID NOT CLOSING.  OVERTEMP SENSOR WOULD THEN POP.  FOUND BLACK SEALANT INSIDE SOLENOID.  FACTORY (JANAERO DEVICES) NOTIFIED IMMEDIATELY.  THIS SOLENOID WAS ON NEW HEATER WITH 120.3 HOURS SINCE NEW.
