Troubleshooting Flow Charts for the Lincoln SCR
In an effort not to duplicate information already in this manual we will use
any of the SCF-Revolution Furnace Troubleshooting Flow Charts that apply
to the Lincoln SCR.
Two Flow Charts specific to The Lincoln SCR are needed.
Convection Blower
Figure 3
The Lincoln SCR utilizes a separate “Normally Open” Heat Sensing Disc to turn the
Convection Blower ON and OFF. The voltage is controlled by the same circuit as the
Combustion fan. It is mounted beside the “Proof of Fire” disc. (See figure 3) The Blower
Switch has Blue wires plugged into it and the Proof of Fire Switch has Brown wires
plugged into it.
