American Standard Silver Series. Approx 5 years old. First time running system in about a month.
- Turned-on thermostat to heat, set temp 2 degrees higher than current temp
- Aux heat cam on temporarily, them turned-off
- Cycle continued
- Temp achieved, cycle completed, pump & air handler turned-off
- Clicking coming from outside heat pump
- turned off thermostat, still clicking
- turned-off breaker at pump, still clicking
- turned-off main break in house panel, clicking stopped.
- turned-back on, cycled normally, then clicking after cycle completed
- took off outside pump service panel. Both Red fault light and green system light flashing.
- I tried to count the fault light blinks for error code, but appear to just be constant.
- pretty loud clicking about the same pace as the flashing lights coming from the circuit board area, or right behind it.
Now the fault light indicator stays lit constantly when the thermostat is turned-off.
