(BL) Combustion Motor:
NOTE: If your meter does not have a hertz scale, please
refer to voltage and resistance readings listed
below. If you have a hertz scale, check the
following items first. Hertz reading across black -
white wires, pins 41 and 42.
RHFE-431 - LP UNITS
RHFE-556 LP UNITS
Lo fire - 44 Hz.
Lo fire - 47 Hz.
Hi fire - 81 Hz.
Hi fire - 106 Hz.
Voltage and resistance check for (BL).
(TH) Thermistor:
Check the thermistor by inserting meter leads into each end of the thermistor plug. Set your meter to the 200k
scale and read resistance. You should be able to apply heat to the thermistor bulb and see the resistance
decrease. Then apply ice to the thermistor bulb and the resistance should increase.
EXAMPLES:
41 °F = 91 k ohms
50 °F = 65 k ohms
68 °F = 39 k ohms
86 °F = 23 k ohms
(FR) Flame Rod:
Flame rod - yellow wire = pin #27. Low fire current should be 1.3 to 2.0 micro amps (F
a).
High fire current should
be 4 to 8 micro amps, depending on gas type being used.
NOTE: I
mproperly setup and/or converted units can soot and cause carbon to accumulate on flame rods. This
will cause hard lockouts. If carbon is found on the flame rod, remove and clean carbon from rod. Then
you will need to confirm manifold gas pressure, proper air dampers and ensure vent is clear. Also, check
for proper orifices.
