WARNING

3.  Using a voltmeter, measure the voltage across the hot 

and neutral connections. 

NOTE:

 To energize the furnace, the Door Interlock Switch 

must be engaged at this point.
4.  No reading - indicates open wiring, open fuse, no pow-

er, or faulty Door Interlock Switch from unit to fused 

disconnect service.  Repair as needed.

5.  With ample voltage at line voltage connectors, energize 

the furnace blower motor by jumpering terminals R to 

G on the integrated ignition control.

6.  With the blower motor in operation, the voltage should 

be 115 volts ± 10 percent.

7.  If the reading falls below the minimum voltage, check 

the line wire size. Long runs of undersized wire can 

cause low voltage. If wire size is adequate, notify the 

local power company of the condition.

8.  After completing check and/or repair, replace Junction 

Box cover and reinstall the service panel doors.

9.  Turn on electrical power and verify proper unit opera-

tion.

WARNING

1.  Check wiring visually for signs of overheating, damaged 

insulation and loose connections.

2.  Use an ohmmeter to check continuity of any suspected 

open wires.

3.  If any wires must be replaced, replace with AWM, 105°C.

WARNING

4.  Induced Draft Motor must run and pull in pressure 

switch.

5.  If the hot surface ignitor heats and at the end of the 

ignitor warm-up period the gas valve opens and the 

burners ignite, the trouble is in the thermostat or wiring. 

6.  With power off, check the continuity of the thermostat 

and wiring. Repair or replace as necessary.

If checking the furnace in the air conditioning mode, pro-

ceed as follows.

7.  With power off, Jumper terminals R to Y to G.

8.  Turn on the power.
9.  If the furnace blower motor starts and the condensing 

unit runs, then the trouble is in the thermostat or wiring. 

Repair or replace as necessary.

10. After completing check and/or repair of wiring and 

check and/or replacement of thermostat, reinstall blow-

er compartment door.

11.  Turn on electrical power and verify proper unit opera-

tion.

CHECKING TRANSFORMER AND CONTROL CIRCUIT

A step-down transformer 120 volt primary to 24 volt secondary, 

40 VA (Heating and Cooling Models) supplies ample capacity 

of power for either operation.
