WISINY RTG20235C Tankless Water Heater Ignitor Coil Black Replacement

Description

Product Overview

The WISINY RTG20235C ignitor coil is engineered specifically for Rheem and compatible Richmond, Ruud tankless gas water heaters that encounter the frustrating error code 11, indicating a failed ignition sequence. Constructed from a high‑temperature resistant alloy, the coil delivers a consistent spark that reliably lights the burner, ensuring uninterrupted hot water flow. Measuring a compact 10.25 × 1.25 × 1 inches and weighing only 1.13 ounces, the part fits seamlessly into the existing housing without requiring any modifications to the heater’s enclosure. The coil operates on a standard 120 V supply, matching the original equipment specifications, and its black finish not only blends with the interior components but also provides an added layer of corrosion resistance for extended service life. Every unit is tested to meet rigorous performance standards, guaranteeing that the replacement will meet or exceed the original manufacturer’s expectations. With a straightforward part number reference—RTG20235C—identifying and ordering the correct component is quick and error‑free, reducing downtime for residential or commercial installations.

Usage

This ignitor coil is intended for indoor installation on floor‑mounted tankless water heaters in residential homes, apartments, small commercial settings, and even in light‑industrial environments where space is at a premium. It is ideal for homeowners who have experienced intermittent hot water due to a faulty ignitor, as well as professional plumbers and HVAC technicians seeking a reliable OEM‑compatible part to restore system functionality. The coil’s design accommodates typical indoor ambient temperatures and can tolerate the occasional temperature spikes that occur during high‑demand periods. Because the coil draws power from a standard 120 V circuit, no additional wiring or voltage conversion is required, simplifying the replacement process. Whether the heater is located in a utility closet, a basement, or a dedicated mechanical room, the RTG20235C coil integrates smoothly with existing mounting brackets and does not interfere with other components such as the gas valve, pressure sensor, or flow meter. Proper installation restores the heater’s ability to ignite on demand, eliminating the need for costly system replacements and reducing energy waste.

FAQ

What does error code 11 mean on a Rheem tankless water heater?

Error code 11 typically indicates a failure in the ignition system, meaning the ignitor coil is not generating the spark needed to light the gas burner. This results in the heater shutting down to prevent unsafe operation. Replacing the ignitor coil with the WISINY RTG20235C part restores the ignition sequence and resolves the error.

Can I install the RTG20235C coil myself, or do I need a professional?

The coil is designed for straightforward replacement and can be installed by a competent DIY enthusiast with basic electrical knowledge. However, because the heater involves gas connections, many installers recommend having a licensed plumber or HVAC technician perform the installation to ensure compliance with local safety codes.

Is the RTG20235C coil compatible with all Rheem tankless water heater models?

The RTG20235C coil is compatible with a wide range of Rheem tankless water heaters that use the standard 120 V ignitor configuration, including many Richmond and Ruud models. Always verify the part number on your existing ignitor or consult the heater’s service manual to confirm compatibility before purchasing.

What warranty does WISINY provide for this ignitor coil?

WISINY offers a one‑year limited warranty covering manufacturing defects. If the coil fails under normal operating conditions within the warranty period, you can contact WISINY customer service for a replacement or refund, subject to proof of purchase.

How do I know if the ignitor coil needs replacement?

Common signs include repeated error code 11 alerts, a lack of hot water even when the heater is powered, and a clicking sound without ignition. If troubleshooting steps such as resetting the heater do not clear the error, the ignitor coil is likely the culprit and should be replaced with the RTG20235C part.
