Tradie Pro Tip

Before you even pull the cover, double-check your diagnostic codes. Sometimes what looks like a board fault is actually just a pressure switch or ignitor acting up. Replacing the right part the first time saves everyone hassle and money.

Pair With

Consider pairing this control board with new gas pressure switches or an ignitor if you're undertaking a broader service on an older Bonaire heating unit. You might also find replacement capacitors useful for other electrical components.
