Walk E113 in Diagnose

2 plates — walk the one on the cabinet

First check

1 Measure at the IFC under load

On Lennox EL195NE line-voltage codes are incoming power. Measure L1/L2 (or L1/N) at the board while it is trying to run, not just at the disconnect. Measure at the IFC. Boost transformer, generator, or utility high.

Expect: Voltage in the rating-plate window under load.

The rest of the walkthrough is Diagnose.

On the plates

  • Measure at the IFC. Boost transformer, generator, or utility high.
  • Resumes ~5 s after voltage is in range.
