Payne Furnace Code 46.1
StatusShown as: 4 short flashes, 6 long flashes; 46.1 on the display
Momentary loss of power. Heating stops and restarts on its own once the power fluctuation is resolved.
Manual wording: “46.1 MOMENTARY LOSS of power - Heating operation will stop and will restart once the power fluctuation is resolved.”
Documented for: PG80MSU
Likely causes, most common first
- Brownout or brief power interruption to the furnace
What you can safely check yourself
- Nothing to fix if you had a power blip
- If it repeats without outages, check that the breaker is fully on and the furnace service switch is not loose
When to call a technician
Frequent 46.1 codes with no utility outages usually mean a loose 115 V connection or a failing door switch - have a technician check it.
A Payne furnace throwing this code repeatedly has a reason — clearing the code without fixing the cause just hides it.
