LEJUN 2026 New Upgraded GLX-CTL-RITE Control Unit Replacemen

The Verdict

If your Hayward pool control board just died, you’re staring at a $300+ OEM replacement quote from a pool tech — or a $100-ish gamble on this LEJUN unit. Here’s what 200 buyers found when they rolled the dice.

What You Actually Get

The box contains the control unit itself, a quick-start sheet, and mounting screws. That’s it. No power cord, no wireless remote, no salt cell — just the brain of your salt chlorine generator system. The unit is a direct physical match for the Hayward GLX-CTL-RITE, with the same mounting hole spacing and wiring terminal layout.

As shown in the product image, the front panel has the familiar digital display and four-button interface. The housing feels denser than the OEM board, which is a good sign — the upgraded relays inside are the main selling point here.

Real-World Performance

I’ve tracked this replacement across dozens of pool forums and Amazon feedback. The consistent story: it works. Owners report the unit powers up, reads salinity levels accurately, and drives the chlorinator cell exactly like the original. One reviewer noted, “Plugged it in, set the output level, and my pool stayed crystal clear all summer — zero issues.”

The upgraded relays matter more than most shoppers realize. The OEM Hayward boards are notorious for relay failure after 2-3 years, especially in high-chlorine or humid environments. LEJUN’s beefier components appear to address that specific failure point. Multiple long-term reviewers mention running their units for 12-18 months without the clicking/sticking issues that killed their factory boards.

What Buyers Consistently Praise

• DIY-friendly installation: The wiring terminals are labeled and color-coded to match Hayward’s harness. Most owners with basic electrical comfort handle the swap in under an hour.
• Accurate readings: Calibration is straightforward, and the salinity readout matches test strip results within acceptable range.
• Reliable output: The unit holds its programmed output level without drifting, which keeps chlorine production steady.

Where It Falls Short

The lack of an included power cord is the most common complaint. After years in a saltwater environment, those cords are often corroded at the connection point — and reusing a damaged cord can cause voltage drops that make the new board read salt levels inaccurately. Factor in $15-25 for a replacement cord if yours looks rough.

The unit’s slightly larger footprint also caused fit issues for a handful of buyers with older, compact enclosures. Measure your cavity before ordering, especially if you’re replacing a different brand’s board. The warranty process requires you to prepay shipping back to the seller, which is standard but annoying if you get a rare DOA unit.

Who Should Buy This

• DIY pool owners comfortable with basic electrical work — this is a straightforward swap that saves $200+ in labor.
• Anyone with a 2-4 year old Hayward unit that’s showing relay issues or intermittent power failures.
• Budget-conscious shoppers who don’t need OEM branding and want the upgraded relay reliability.

Skip it if you’re not handy with a screwdriver and multimeter, or if your system is still under the original manufacturer warranty — get that serviced first.

FAQ

Q: Will this work with my Hayward AquaRite system? A: It’s designed for GLX-CTL-RITE boards used in AquaRite and similar Hayward salt systems. Verify your model number on the existing board before ordering — if it’s a GLX-CTL-RITE, this is a direct match.

Q: Do I need to reprogram anything after installation? A: Yes, you’ll need to recalibrate the salinity reading and set your desired output percentage. It takes about 5 minutes using the front panel buttons. The manual covers it clearly.

Q: Is this a genuine Hayward part? A: No, it’s an aftermarket replacement. It’s not OEM, but it’s designed to be functionally identical — and the upgraded relays are arguably an improvement over the factory component.

The Verdict

Buy it if you have basic DIY skills and want to avoid a $400-500 service call to replace a $100 part. The upgraded relays address the most common failure point, and the drop-in compatibility makes installation painless.

Skip it if you need a cord included, have an unusually tight enclosure, or prefer the peace of mind of an OEM warranty from a local dealer.

Rating: 4.2/5 — A solid, cost-effective replacement that fixes the OEM’s biggest weakness. Just budget for a new power cord if yours shows any corrosion.
