The pressure regulator is factory set at 4" W.C. (0.99 kPa) for natural gas and 10" W.C. (2.48 kPa) for propane gas. 
To check the manifold pressure: 

1.  Turn all thermostats and burner valves to OFF position. 

2.  Turn main gas valve to entire range off. 

3.  Remove valve panels and locate the small plug in the manifold. 

4.  Remove plug and install a fitting appropriate to connect a manometer. 

5.  Turn on main gas to range and light pilots. 

6.  Turn all burners and ovens to full ON position and read manometer. 

7.  If manometer does not read 4" W.C. (0.99 kPa) for natural gas, or 10" W.C. (2.48 kPa)  for propane gas, adjust 

regulator (if gas pressure is correct go to Step 10). 

8.  Remove cap from top of regulator. 

9.  With a screwdriver rotate regulator adjustment screw clockwise to increase, or counterclockwise to decrease, 

pressure until manometer shows correct reading. 

10.  Repeat steps 1 and 2. 

11.  Remove manometer fitting and replace plug in manifold. 

12.  Turn on main gas to range and light pilots. 

13.  Replace valve panels.

Is there voltage? 

No 

Yes

Remove the wire terminal cover from the blower motor. 

Check all wiring for loose terminals or breaks. 

Check that the common wire is connected to the motor black wire. 

Reconnect the power supply and turn on blower-control switch.  

Use a voltmeter to measure the voltage between the black wire and 

the white wire.

Remove the wire nuts from the red, white, and black wires.  

Check that the resistance across the white and black wires is 

approximately 1.9 ohms. Check that the resistance across the  

white and red wires is also approximately 1.9 ohms. If either 

resistance is incorrect, replace the blower motor. 

Check that the red wire is capped off. 

Remove the wire nuts from the black and the white wires. Check 

that in each case the wires are twisted together securely. 

Check that the neutral wire is connected to the white wire.
