TIFFIN MOTORHOMES –PHAETON® Chapter 4 MAJOR APPLIANCES & ACCESSORIES
> Check flame site hole to see if igniter is sparking from the probe to the burner. Bend ignition wire to adjust to
proper gap or contact the manufacturer or the nearest authorized service representative.
There is no ignition. Red LED is flashing a series of seven flashes.
The ignition has locked out. Check for these possible causes:
> Locate the high temperature switch (two light blue wires) at the upper right hand of the heat exchanger.
Push the reset button in the center of the switch. (Early models only; newer models have an auto reset).
> Check that the yellow ignition wire is clipped to the spark electrode terminal and is not touching anything else.
Check that there are no cuts or breaks in the yellow wire. Align it so that it is not in contact with anything
but the terminal.
> Excessively high or turbulent winds may cause the burner to extinguish. Adjust the position of the vehicle
relative to the prevailing wind.
Heater turns on but temperature fluctuates erratically.
> Hot and cold water lines are reversed on back of heater. If the flow meter rotor is not rotating counterclockwise,
pipes are connected in reverse. Be sure hot water is connected to bottom fitting and cold to the top fitting.
> May be caused by excessive restriction at the water outlets, showerheads, aerators or water strainers.
These should be cleaned and the showerhead flow restrictor removed as defined in “Recommendations for
Water System Installation.”
> The Variflame gas modulating valve is out of calibration. Consult the manufacturer. Heater does not ignite
when water is turned on.
> The gas flow may be too low due to an improper gas line diameter (under 3/8” outside diameter). The gas line
may be excessively long (over 20 feet) or the on/off solenoid at the tank (if you have one) may have an orifice
that is too small (under 3/16” of an inch).
Heater comes on but rapidly cycles on and off.
> Water flow is too low. Increase flow at a tap. Clean all aerators and shower head screens.
> Water pump is not functioning properly. Repair or replace pump.
> If the heater cycles as the pump cycles, a pressure accumulator tank is needed in the water system. If you have
an accumulator tank, check to see if it has become filled with water. If it has, drain it so that it contains air only.
> Air is in the water line. Bleed air by turning on all water taps.
