Product details
The Sta-Rite 42001-0056S is the replacement terminal board for the Max-E-Therm SR-200, SR-333 and SR-400 pool heaters. It is a new OEM part.
What it does
The terminal board is the landing point for heater wiring inside the electrical section. Power, controls and the safety circuit all connect through it, so its condition decides whether the rest of the electrical system sees clean connections.
When to replace it
Terminals that run hot corrode, loosen and eventually burn. Once a board is scorched, discolored or has melted insulation at a terminal, cleaning it up is not a repair. Replacing the board restores solid connections and removes a fault that tends to come back worse.
What is not included
This listing is the terminal board alone. The board fuse, ignition control module, transformer and air flow switch are all separate Sta-Rite parts.
