Quick answer: A pool heater’s control board is the central circuit board that manages ignition sequencing, safety interlocks, and (on most models) the digital display — and it’s one of the few parts on this site we recommend leaving to a technician, not because of gas-line risk like the gas valve, but because the replacement board has to be configured to your exact model and fuel type after install. For Raypak Digital heaters the OEM part is 013464F (roughly $400); Pentair MasterTemp and Max-E-Therm use 461105 (roughly $480-$580); Hayward Universal H-Series uses FDXLICB1930 (roughly $447); and Zodiac/Jandy JXi heaters use the R0456900 ignition control board (roughly $467-$614). Pool-repair-industry sources cite power surges and moisture intrusion as the two most common failure causes — and a board swap is usually one of the last things a technician checks, not the first.
Why this one isn’t a typical DIY parts swap
Most of the OEM-parts guides on this site — igniters, pressure switches, high-limit switches — cover components a homeowner can swap with a screwdriver and the right part number. The control board sits in a gray area. There’s no gas line involved, so it doesn’t carry the same hard “don’t DIY this” warning as our gas valve guide. But according to pool-repair-industry sources, a new control board typically has to be set via DIP switches or rotary dials to match your heater’s exact model, BTU size, and fuel type (natural gas vs. propane) before it will run correctly — get that wrong and the heater won’t fire, or worse, won’t fire safely. The board is also electrostatic-discharge (ESD) sensitive; installing it without proper grounding is a documented cause of a brand-new board failing on first power-up. That’s a technical-competence risk rather than a safety risk, which is why we’re calling this one “technician recommended” rather than “don’t DIY” — but it’s a meaningfully bigger job than the igniter or switch swaps elsewhere on this site.
Pool heater control boards at a glance
| Control board | Fits | Price |
|---|---|---|
| Raypak 013464F | Digital 185B-407A | ~$400 |
| Pentair 461105 | MasterTemp / Max-E-Therm | $480-$580 |
| Hayward FDXLICB1930 | Universal H-Series | ~$447 |

1. Raypak 013464F — For Raypak Digital Heaters
Raypak 013464F Control Board
- The OEM control board for Raypak's Digital line, the same heaters covered in our best Raypak pool heater roundup.
- Superseded/kit-packaged by Raypak as part number 100-10000345 at some suppliers — confirm which number your model calls for before ordering.
- Raypak's own installation documentation requires DIP-switch settings matched to your model, BTU size, and fuel type after the board is installed; skipping this step is a common cause of a "new board, still won't fire" callback.
- Not a gas-line job, but the model-matching and ESD-sensitivity concerns make this one worth having a technician handle.

2. Pentair 461105 — For MasterTemp and Max-E-Therm
Pentair 461105 Control Board
- The current OEM control board for Pentair's MasterTemp and Max-E-Therm lines, superseding the older 42002-0007S part number — both show up in retailer listings, but 461105 is the current one Pentair ships.
- The same shared electronics platform covers Sta-Rite's rebadged version of this heater line, so the part number carries over if you own that badge instead.
- Two independent retailer listings landed within about $100 of each other ($479.95-$579.99), a tighter spread than some of the other OEM parts on this site.
3. Hayward FDXLICB1930 — For Universal H-Series
Hayward FDXLICB1930 Control Board
- The OEM integrated control board for Hayward's Universal H-Series line, the same heaters featured in our best Hayward pool heater roundup.
- Listed under Hayward's own catalog number 6223-175 as well as the FDXLICB1930 part number, which makes it easier to confirm you're buying a genuine OEM board.
- Watch for heavily discounted used or incomplete-kit listings well under $300 — we found one outlier around $225 that wasn't a like-for-like new OEM board, which is why we're not citing it as a real price point.
4. Zodiac/Jandy R0456900 — For JXi Heaters
Zodiac/Jandy R0456900 Ignition Control Board
- JXi heaters actually split control functions across multiple boards — this ignition control board handles firing sequencing, flame sensing, and gas-valve actuation, but there's also a separate power interface board and power distribution board on the same heater.
- If your technician's quote references a different board on a JXi unit, ask which specific function failed before assuming this is the right part — Jandy's multi-board layout isn't a direct 1:1 match to the single-board setup the other three brands use.
- Retailer pricing has the widest spread of the four brands here ($467-$614), so it's worth comparing more than one listing.
Why control boards fail
Pool-repair-industry sources point to two causes far more often than any others. Power surges — voltage spikes from storms or grid fluctuations — can damage a board’s microprocessor or communication circuits, especially on heaters without dedicated surge protection ahead of the control panel. Moisture intrusion is the other big one: condensation or a poorly sealed cabinet lets water reach the board over time, corroding traces and relay contacts until the board fails intermittently or outright. Reported lifespan varies by source and climate — commonly cited in the 5-15 year range — which is wide enough that we’re not presenting it as a firm number to plan a replacement around.
What a fair quote looks like
The board itself runs roughly $400-$600 depending on brand, but that’s not what you’ll pay all-in. A full installed replacement — part, labor, and the post-install configuration a technician handles — is one of the pricier single-part jobs on a pool heater; our repair cost guide puts a control-board job in the $600-$1,200 range, in the same tier as a gas valve replacement. If a quote comes in well above that, it’s worth asking whether the technician is also replacing a related failed part (a fried board can sometimes take an igniter or sensor down with it in a surge event) before assuming you’re being overcharged.
The bottom line
A pool heater control board isn’t cheap — $400-$600 for the part alone, more once labor and configuration are added — and unlike most of the other OEM parts on this site, we’re not telling you to grab the part number and do it yourself. The DIP-switch model matching and ESD sensitivity make a mis-installed board a real risk of an expensive do-over. Knowing the OEM part for your brand — Raypak 013464F, Pentair 461105, Hayward FDXLICB1930, or Zodiac/Jandy R0456900 — mainly protects you from an inflated or wrong-part quote. And before you or a technician gets to the board at all, our not-heating troubleshooting guide covers the cheaper, more common causes worth ruling out first. If it’s just the display or buttons acting up while the heater still ignites and heats fine, check our control panel and keypad guide first — on every brand but Raypak, that’s a separate, cheaper part than the board.
