Do not attempt to adjust the gas input by adjusting the regulator setting. The correct gas regulator setting is required to maintain proper combustion and must NOT be altered Review: It fixed my heater! Super easy to swap out - I was quoted $850 from a pool service company to replace the board on my Master Temp heater and I was hesitant to do it because my heater manufacture date sticker says it is 17 years old ...! The guys at the pool company agreed it may not be the best idea to invest in that heater and in a last ditch effort to buy me some time before I spend $5000 on a new unit was to order this 'used/good' Pentair board for less than half the price of a new one. It was here in 2 days and it took me about 10 minutes to pop it in to my heater ... I had the whole thing apart anyway so it was just a matter of pulling each connector off the original board and attaching it to the new one. It fired right up and my heater is working great! Review: An upgrade, I guess - Have the older Max E Therm pod. Everything and I mean everything on desertcart is for the newer models. This is the only one I could find the correct leads/connectors. Display is better with more menu options, but kept throwing HLS codes. Replaced HLS sensor and got even more codes. So I bypassed the HLS (Google is your friend) at my own peril until I can find a compatible HLS. Otherwise works great. ## Features - PCB, Pentair Max-E-Therm Nat./LP, Control. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #592,505 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #1,013 in Swimming Pool Heater Parts | | Customer Reviews | 4.3 out of 5 stars 468 Reviews | ## Images ![Pentair PCB, Max-E-Therm NAT./LP, Control - Image 1](https://m.media-amazon.com/images/I/614DPKirs1L.jpg) ![Pentair PCB, Max-E-Therm NAT./LP, Control - Image 2](https://m.media-amazon.com/images/I/61TLlYOh3dL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ It fixed my heater!

The controls no longer worked I wasn't sure if it was just the membrane pad or the controller itself. Had a pool guy test and he told me I needed a new board. This was a drop-in replacement. The main difference, however, is this product has switched to a LCD display (like a calculator or old-school digital watch). My existing membrane control had a red tint and it meant I couldn't easily read the display. So I purchased a new membrane pad with a clear window to go along with it. DIY installation is pretty straightforward. Unscrewed the front and back panels, unscrewed the top, yanked all the connectors out and plugged into new one. Pulling the connectors was probably the hardest part. ## Frequently Bought Together - Pentair 42002-0007S Control Board Kit Replacement NA and LP Series Pool/Spa Heater Electrical Systems - Pentair 472610Z Switch Membrane Pad Replacement MasterTemp Pool and Spa Heater Electrical System - Pentair 42001-0053S Electrical Systems Thermistor Replacement Pool and Spa Heater --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/2183217-pentair-pcb-max-e-therm-nat-lp-control](https://www.desertcart.co.uk/products/2183217-pentair-pcb-max-e-therm-nat-lp-control) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-29*
