idle / Ht / CF / CL1
StatusStatus, not a fault
Normal run states. idle = standby. Ht = heat running (a rate, not Ht1 vs Ht2). CF = continuous fan. CL1 = low cool.

First check
1 Confirm this is not a fault
On the Goodman GMVM97 this readout (idle / Ht / CF / CL1) is run status, not a lockout. Write what the display actually shows and whether W/Y/G is present at the IFC.
Expect: Idle / Ht / CF / stage+CFM words change when you apply and remove the call.
If fail: If the word never changes on a real call, the call is not reaching this IFC.
If pass: The board is alive. Diagnose the comfort complaint, not this code.
The rest of the walkthrough is Diagnose.
On the plates
- Do not replace the board because it says idle or Ht.
- A communicating request sitting at idle is bus / fallback, not a bad modulator.
- There is no Ht2 to wait for. If capacity will not climb, look at high-rate prove (E8/E9) and the valve, not a W2 wire.
