(FM) Convection Fan Motor: (Connector E)
Variable 100VAC Motor 60 Hz
Read voltage across:
Voltage Potential
Read resistance
Pin Numbers
Black-Red 37-105
VAC
100-120
Ω
Pin
#1-2
* Be sure to check for obstructions to blades. Check the capacitor before replacing motor.
(PS) Pressure Sensor:
(Connector A) Omron Electronic Pressure Switch
Omron Electronic
0.31 in (8.0 mm) WC
ON
0.11 in (2.8 mm) WC
OFF
5 VDC
Note: Insure clear and black hose from pressure switch to blower air chamber is not blocked or
crimped with any obstructions including spider webs.
(TF 216ºC, OHS1 90ºC, OHS2 70ºC)
(Connector G) Safety Circuit:
Disconnect connector G from PCB. Check for continuity reading from Pin #1 to Pin #5 on the wiring
harness White to White wires. If you do not read continuity through this circuit, locate open thermal
fuse, bimetal OHS1, or bimetal OHS2, and replace. You must immediately determine what caused
the overheat situation and correct. Check combustion specifications, gas pressures, gas type, and
for any obstructions to air flow.
(R.TH) Room Thermistor: (Connector H)
Negative Co-efficient Thermistor
(the resistance decreases as the temperature increases)
Disconnect connector H from PCB. Set your meter to the 200K
Ω
scale. Place your meter leads into
Yellow to Yellow. Apply heat to the thermistor bulb. The resistance will decrease. Apply cold and the
resistance will increase. Examples of readings:
41ºF=91K
Ω
50ºF=65K
Ω
68ºF=39K
Ω
86ºF=23K
Ω
(OH.TH) Over Heat Thermistor: (Connector H)
Disconnect connector H from PCB. Set your meter to the proper
Ω
scale. Place your meter leads
into White to White. A reading below 0.38k
Ω
indicates a short. A reading above 1255k
Ω
indicates
an open circuit or broken wire. Insure air flow is not obstructed.
(FR) Flame Rod
(Connector C1)
Set your meter to read micro-amps (µ). Disconnect connector C1 and place your meter in series
with the Yellow to Yellow wires. Upon flame development you should read 1 -2 micro-amps.
Depending on gas type and firing rate you should read 4 to 8 micro-amps. You must have a
grounded and polarized electrical supply with no obstructions in burner or build up on flame rod to
proof flame. The micro-amp symbol on your meter is µ.
(Hard Lock Out Information)
Improper sized gas lines, low pressure drops, defective or freezing pressure regulators, improper
electrical supply and failure to ground, spider webs in burners, intake and exhaust air blockage of
vents, broken or damaged wiring harnesses, or blown fuses can cause hard lock outs. Before
replacing components in furnace, insure the above items are within the specifications. The above
listed items are not a warranty issue or defect in unit.
