American Standard S9V2 E2.2 is recycles exceeded. Flame was sensed, then lost, and the control locks out for one hour after 10 times. E2.1 is flame that was never sensed, after 3 times. The sequence in this guide measures flame current on the FP pads, typically 0.75 to 3.0 microamps. That measurement is technician work.
Likely causes
- Flame sensed, then lost, until the recycle limit is exceeded
Safe checks for E2.2
- E2.2 is not E2.1. E2.1 is flame never sensed. E2.2 is flame that proved and then went away
- Technicianthe heating sequence in this guide proves flame at the flame sensor within 4 seconds, typically 0.75 to 3.0 microamps
Capacitors can hold a charge after the power is off. Safety terms.
When to call a pro
Call a licensed HVAC technician if the burners light and then drop out until E2.2 locks out for an hour.
