    York heater troubleshooting
    I have a york diamond 90 model P3UR
    When I raise the temp, the blower goes on, then I see the pilot get hot ( glow ), then blower goes on for about 30 seconds and shuts off. This goes for 3 cycles then stops. Can anyone help? Thanks

    Try cleaning the flame sensor with fine sand paper or steel wool.
