If your Honeywell furnace has been displaying error code r7284, there are a few common solutions to the problem. The first option is to reset the unit manually. The reason for this is the same as the first one: a faulty CAD cell or faulty oil valve. If there is no heat in the unit, it means the ignition is out of sequence or the flame is premature. To remedy the problem, it is important to follow the steps outlined below.

In the case of Honeywell r7284 error codes, the most common cause is an improperly connected CAD cell. The CAD cell senses the presence of the burner flame to control the oil supply. If the CAD cell is out of phase, the oil may get stuck in lockout mode. If the CAD cell is too high, the unit will begin to fail. If this continues, the unit will shut down completely.
