    Why is the green power light blinking on my Alpine ALP150B Boiler control?
    • M
      mariaharperAug 26, 2025
      A blinking green power light on the control indicates a control fault. The internal power supply is repeatedly starting and stopping. Try disconnecting all terminals except 24VAC to power the Control. The green light should be steady. If it is not, then the control is defective. If steady, start plugging in all the connectors while watching the green light. When faulty wiring reconnected, green light will begin to flash.

    What to do if my Alpine ALP150B Boiler is not responding to heat call?
    • J
      Joseph MasonAug 23, 2025
      If your Alpine Boiler isn't responding to a call for heat and the status and priority show standby, the boiler isn't detecting the call for heat. Check the thermostat or zone wiring for loose connections, miswiring, or a defective thermostat/zone control.
