My guess is they like the soy in the wires. It's an easy replacement and the pool's functioning again. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great value for a replacement Stack Flue. Not OEM. *by S***K on Reviewed in the United States on November 17, 2023* Easy enough to install yourself in under 5 minutes. Lot cheaper than paying over $100 for this part. Installed mine on Nov. 13, 2023. So far, so good. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Outstanding *by J***I on Reviewed in the United States on October 23, 2023* Replaced the bad one with this one. The outdoor heater worked right away, and it has been lasting for more than three years so far without any issue. --- ## 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.in/products/673729-pentair-42002-0024s-stack-flue-sensor-replacement-pool-and-spa](https://www.desertcart.in/products/673729-pentair-42002-0024s-stack-flue-sensor-replacement-pool-and-spa) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-06-19*
