The 304286 is a fan timer control board designed for use with some of the following Armstrong & Brown HVAC blowers: XDP/XDPII, XEIV, XHV/XHVI, and XXIV.

54701 HOVFAN TIMER BLOWER CIRCUIT BOARD. MODELS 1079SA, 2268SA, 2468SA NOTICE: NOT FOR USE WITH MODEL 1063RV. IF THE FAN SWITCHES TO LOW SPEED BEFORE THE TIMER HAS COMPLETED YOUR SELECTED DELAY TIME, REPLACE THE TIMER.

The Armstrong Air 304286 blower control circuit board features on/off/auto switch, LED indicator light for fan mode selection, and relay circuit board enclosure.

The 302 Series is a single-phase outdoor, low-pressure fan and blower control board with built-in amplifier. The Board will automatically restart after power interruption.

Our blower control circuit boards have been engineered to the original design and will provide the expected performance of the fans.

Your fan won't always turn on. See symptoms in the chart below. THEN this is the part you need. Test it before you install it, by doing this: Unplug the wires from the blower motor (in the basement). Turn the power back on. If the blower motor works, then it's not this board and you can install a new one without worrying about rewiring.

In rare cases this part should be replaced. If the blower will not cycle on and off at the correct times, or if the motor functions intermittently, replace this board. This would be due to a failed BLOWER TIMER.
