Carrier 58MVP Error Code 11: No Previous Code
What Does Code 11 Mean?
When you retrieve status codes on the Carrier 58MVP and it flashes code 11, the control board is reporting that there is no fault in memory. Carrier's guide notes that stored status codes are erased automatically after 72 hours, so an 11 often just means enough time has passed since the last event, or the furnace has been running trouble-free.
This is useful confirmation during troubleshooting. If a homeowner reports an intermittent problem but the board shows 11, the fault either did not store, self-cleared after 72 hours, or was cleared by a power reset. On this variable-speed control, reading 11 rules out any latched fault and steers diagnosis toward intermittent or external issues — the thermostat, power, or airflow — rather than a component the board has flagged.
What You'll Notice
- The control board flashes code 11 when stored status codes are requested
- The furnace otherwise operates normally with no lockout
How This Is Diagnosed
Code 11 is read by retrieving the stored status codes; seeing 11 confirms the diagnostic memory is empty. Keep in mind that any real fault clears itself after 72 hours or after a power cycle, so an 11 shortly after a reported problem does not always mean nothing happened — the earlier code may simply have aged out of memory.
- An intermittent problem keeps recurring even though the board shows code 11, which makes the fault hard to capture
- You need help reading or interpreting the blink codes on the control board
Frequently Asked Questions
What does code 11 mean on a Carrier 58MVP?
It means "no previous code" — there is no stored fault in the board's memory. It is a normal, healthy status.
My furnace had a problem but shows code 11 — why?
Stored codes erase automatically after 72 hours and also clear on a power reset, so an earlier fault may have aged out of memory before you checked.
