Overview

When a Rheem, Ruud, or Richmond tankless gas water heater hesitates to light, the ignition coil is often the culprit. The Wisiny RTG20235C ignition coil replacement is designed to address these ignition symptoms while fitting a range of popular models. This part aligns with the PLM-112 replacement coil family and is built to withstand the heat and cycling inside a modern tankless system. While no part can guarantee ignition every time, a healthy coil can help restore more consistent light-off, so you are less likely to run out of hot water during busy mornings.

What is included and how it fits

  • Compatibility: Designed for Rheem tankless heaters, with compatibility for Ruud and Richmond models; includes the PLM-112 family alignment for a proper fit.
  • Durable construction: Robust materials and design to stand up to regular ignition cycles and heat exposure.
  • Verified operation: Suitable for voltage checks and simple installation to verify ignition function.

Key benefits in real life use

  • More reliable ignition, reducing cold-water inconvenience during morning routines.
  • Broader model compatibility means fewer parts to stock for common systems.
  • Longer-lasting ignition components can reduce service interruptions and maintenance calls.
  • Clear guidance and responsive after-sales support help you complete the replacement with confidence.

Usage notes and installation tips

Important Note: This RTG20235C ignitor coil is intended to address error code 11 on compatible Rheem tankless water heaters. If the igniter fails, the burner will not light. It is recommended to pair this coil with the PLM-112 replacement part for a complete fit. After purchase, WISINY offers assistance if you have questions during use.

For best results, follow standard safety practices: shut off gas and power, confirm the heater is cool, and verify the ignition voltage before operation. If you are unsure, contact WISINY support for guidance.
