## Description

This flame sensor is a direct replacement for many Rheem, Ruud, and Weatherking residential furnace models. It is designed to be compatible with the factory ignition systems and provide reliable operation. This part replaces Rheem Ruud Weatherking Comfort Aire Century part numbers 62-23543-01 and 62-23543-03. Please note in the photo that the mounting hole is at approximately the 2:00 O' Clock position with the offset pointing toward the left. Do not clean flame sensors with sandpaper- the grit will melt into glass and the sensor will not work. Clean flame sensors with steel wool or a Scotchbrite pad. This part is covered by the exclusive Duralight two year limited replacement policy. If this part fails within two years from date of purchase, return the defective part and a copy of the original invoice to the place of purchase for replacement. Contact the authorized Duralight dealer that you purchased the part from for details. Original equipment manufacturer's brand name(s) and part numbers are used for identification purposes only. This item is supplied by OneTrip Parts and meets or exceeds original equipment specifications.

Review: Outstanding product, and a great price too. - Well, in 2010 and 2012 I had new flame sensors installed on my furnace. The cost was over $300 each time. I watched the tech install the flame sensor, and it took him at most 4 minutes. I was tired of being ripped off. I purchased this product, installed it in 5 minutes (very simple to do). Works perfect, and I saved the old one since it still works fine. Paid just $18. for it. Saved over $300. because I installed it.
Review: Senses flame as it should - Nothing fancy here, but I am happy to say that the flame sensor ceramics and metal end up sending the right signals (whatever those may be) to my RUUD natural gas furnace. I tried cleaning my old one, but that didn't work, so I purchased this one on desertcart. It works great and has not sent a false signal yet. Cheap and very easy to replace yourself.

### ⭐⭐⭐⭐⭐ Flame sensor ordered for Rheem unit out of control.
*by B***D on April 7, 2014*

Upon reading the information, and several problems other customers had with their unit's, I had the same problem. I cleaned the flame sensor and this helped for a time. From time to time the problem repeated it's self, not all the time. I ordered the flame sensor to have it on hand and today I installed it as the fan would run in the off position. I removed the shroud that held in the kill switch in , the only way to stop it from running. It took about 10 minutes to install it, now the unit runs perfect. I highly recommend this part. Thank you. Burton Howard
