Common Symptoms of a Failed Furnace Control Board

• Furnace will not start
• Hot surface ignitor does not energize
• Inducer motor does not operate correctly
• Gas valve does not receive power
• Blower motor does not operate correctly
• Furnace starts but does not complete the heating cycle
• Intermittent furnace operation
• Control board displays fault codes

Other furnace components can cause similar symptoms, so the control board should be properly diagnosed before replacement.

CNT07541 Replacement Control Board

If your existing Trane or American Standard furnace control board is marked CNT07541 / CNT7541, the CNT07941 is listed as its replacement.

The CNT07941 also replaces several older board numbers, making those cross-reference numbers important when identifying the correct replacement.
