Check Safety Controls
3.5
3.3
The flame sensor, gas valve, and pressure switch were all checked in the
A11253A
Start-up procedure section as part of normal operation.
1. Check Main Limit Switch
This control shuts off combustion system and energizes
air-circulating blower motor, if furnace overheats. By using this
3.7
method to check limit control, it can be established that limit is
3.4
3.2 functioning properly and will operate if there is a restricted
3.6
return-air supply or motor failure. If limit control does not function
3.4
3.7
during this test, cause must be determined and corrected.
3.4
a. Run furnace for at least 5 minutes.
3.2
3.7
b. Gradually block off return air with a piece of cardboard or sheet
3.4
3.2 metal until the limit trips.
3.6
c. Unblock return air to permit normal circulation.
3.8
3.6
d. Burners will re-light when furnace cools down.
3.4
3.7
2. Check Pressure Switch(es)
3.4
This control proves operation of the draft inducer blower.
3.8
3.5
a. Turn off 115-v power to furnace.
3.8
b. Disconnect inducer motor lead wires from wire harness.
3.5
c. Turn on 115-v power to furnace.
