Stuck on a part, a model number or a fix we haven't covered yet? Ask us here. We read the maker's manuals and support pages, email you an answer, usually within a day or two. If you say it's OK, we also post the useful ones on Reader answers so the next person with the same problem finds it too.
What helps us give a good answer
- The brand and model number. Most "which part fits?" questions come down to this.
- Any number printed on the old part, if you've already taken it out.
- What you've already tried, so we don't send you back to step one.
Who answers?

The WH2L Hub team, the same people who write the guides. We work from manufacturer manuals, spec sheets and support pages, link every one of them, and say so when we can't find a clear answer. We don't test products hands-on.
Published answers are signed by Ollie, our cartoon owl mascot. He reads the manual so you don't have to, but he's a drawing, not a real person, so you always know an answer came from the site and not from someone with a made-up name. Meet Ollie.
Not for emergencies. If you smell gas, see sparks or smoke, or water is coming through a ceiling or wall, shut it off if it's safe to do so and call your utility or a licensed pro now. Don't wait for an email.
