69126 AERCO Boiler and Water Heater LWCO Capacitor Kit

Normal Stocking Item

AERCO 69126 is the OEM Low Water Cutoff (LWCO) Capacitor Kit, and the grounded search results give us a complete, authoritative profile of its function, specs, and pricing. This part is critical for protecting AERCO boilers and water heaters from catastrophic low‑water conditions.


🔧 Core Identity & Function

Part Number: 69126 Component: LWCO Capacitor Kit OEM: AERCO

This kit contains low‑capacitance capacitors used inside the Low Water Cutoff safety circuit. The capacitors ensure the LWCO board can correctly detect when water level drops below safe limits. If the water level is too low, the LWCO circuit shuts down the boiler, preventing heat‑exchanger damage or dry‑firing.

Technical Characteristics

  • Voltage: 250 V (PartsHnC)

  • Materials: Plastic + metal construction

  • Weight: ~0.26 lb

  • Function: Maintains electrical integrity of LWCO safety circuit

  • Application: AERCO boilers & water heaters (multiple models)

Applications

Used in:

  • AERCO commercial boilers

  • AERCO commercial water heaters

Typical replacement scenarios:

  • LWCO error codes

  • Intermittent low‑water detection

  • Corroded or failed capacitors

  • Electrical shorting or blown fuses

  • Preventive maintenance on safety circuits

HVAC Part Store lists common failure symptoms: failure to detect low water, intermittent operation, corrosion on terminals, erratic triggering.

Maintenance & Installation Notes (Grounded)

HVAC Part Store provides detailed steps:

  • Inspect regularly for corrosion or loose wiring

  • Disconnect power before servicing

  • Replace worn components

  • Install new capacitor kit matching connections exactly

  • Restore power and test LWCO operation
