Product details
Sta-Rite 32850-0099 is the terminal board fuse for the Max-E-Therm SR-200, SR-333 and SR-400 heaters. It is a new OEM Sta-Rite part, and it is also listed within the Pentair MasterTemp gas heater electrical and burner system parts.
What the fuse protects
The terminal board carries the low voltage control side of the heater. The fuse sits in that circuit so that a surge, a shorted sensor lead or a failed component opens the fuse rather than cooking the board behind it. That makes it a deliberately cheap sacrificial part in an assembly that is not cheap at all.
When to suspect it
A Max-E-Therm that shows nothing on the panel, with power confirmed at the heater, is a classic blown terminal board fuse. Checking the fuse takes minutes and rules out the least expensive cause before anyone starts pricing a control board.
Do not stop at the fuse
If the replacement opens again right away, the fuse is doing its job and reporting a real fault. Trace the short or the failed component before fitting another one, because repeat fuse failures are a symptom rather than the problem.
