Whirlpool Flame Lock water heaters, reviews, troubleshooting, repair and support.

Hi all! My parents have a 2015 Whirlpool n40t121-403 that is sporadically heating. Works fine one minute/day/week, then quits heating. Status light is normal and pilot light is on, and if I bump the thermostat up a bit it kicks on and starts heating. Yes, I know it’s ten years old, but they just bought a car plus my dad has been in the hospital for two weeks now and I am trying to save them some money if possible. Can it be fixed? Is it one of those “parts unavailable” things? Thanks for any help you can give!

You would be wiser to get a rheem gas heater and change it out yourself than to fool with attempting
to get parts for it

Okay, thank you! Not sure I want to mess with installing a gas water heater, but my dad put this one in ten years ago, so I could likely do it. Thanks for the reply!

Hey Tim,

It sounds like you've had quite the experience with your Whirlpool Flame Lock water heater. While your temporary fix might be providing some airflow, it’s not a long-term solution. If you’re looking for a more reliable and safe way to manage air intake and prevent overheating issues, consider investing in a GreenpacTank. They’re known for their durable, well-ventilated water storage solutions that can help regulate temperature and airflow more effectively.
