I HAVE A JANITROL NATURAL GAS FURNACE HOOKED UP WITH AN A/C COOLING UNIT PLACED ON ROOF OF BUILDING. THIS IS HOW I BOUGHT THE CONDO UNIT.
IT IS ABOUT 10-12 YEARS OLD.
THE PROBLEM IS WITH THE HEATING UNIT.
AT STARTUP:
1 THEROMSTAT IS IN OFF POSITION AND FAN IS ON AUTO.
2 THERMOSTAT IS SWITCHED TO HEAT.
3 THE SPARK IGNITION CLICKS ABOUT 6-7 TIMES AND THE SYSTEM WORKS FINE
WHEN THE TEMPERATURE IN ROOM MEETS THE THERMOSTAT SETTING THE SYSTEM SHUTS DOWN FINE.
NOW HERE WE GO.
TEMPERATURE OF THE ROOM DROPS, THERMOSTAT SENDS SIGNAL TO THE UNIT. THE SPARK IGNITION CLICKS ABOUT 7-8 TIMES WITH A NORMAL BEAT. AFTER ABOUT 8 CLICKS IT THEN CLICKS VERY FAST AND INCONSISTENT. ABOUT THREE SECONDS THEREAFTER IT SHUTS DOWN THE SPARK IGNITOR AND WILL TIMEOUT AND THE FURNACE WILL NOT LIGHT.... NO HEAT
THE ONLY WAY FOR IT TO LIGHT IS TO COMPLETELY SHUT DOWN THE FURNACE. ..... SET THERMOSTAT TO OFF . ......WAIT A FEW MINUTES THEN TURN THERMOSTAT TO HEAT. THIS OPERATION IS MANUAL AND DEFEATS THE AUTO STARTUP.
ANYONE WITH THIS EXEPRIENCE LET ME KNOW THE SOLUTION....
