Rated 4.4 out of 5 by 20 reviewers.
Rated 1.0 out of 5.0 by Not quite "universal" (left vs. right hand thread) Beware: If you have a natural gas water heater manufactured by American Water Heater Company, with a model number beginning with "FG", that this thermocouple will not fit your water heater. The connector on the original thermocouple that attaches to the control valve has left handed threads, where the connector on this replacement part has right handed threads. Save yourself a lot of time and hassle by first checking the threads on your existing thermocouple and compare to the threads on the replacement thermocouple before you attempt replacement.

Rated 5.0 out of 5.0 by Great - Saved holidays. Saturday morning wake up because room was too cold. Checked the thermostat and found heating is not working, called couple of guys and was told because of holidays the best we can do is on Wednesday. Or emergency fix can be done on Monday. Anyway found one person and he spend couple of hours and told me I need to replace the furnace because motor and valve are not working and it is better to replace instead of fixing. I noticed when he light up pilot and as soon as he release the knob pilot shutoffs. Googled the issue and found that thermocouple might be an issue, went to HD and the guy greeting on the door saw old one in my hand told me oh thermocouple go to isle 30. Found it there, took me around 15 minutes to replace and bingo furnace back in to business. Good product worked great. Saved holidays December 22, 2012
Rated 5.0 out of 5.0 by No HOT water After a hard day doing yard work I was looking forward to a nice shower. But there was a problem, no hot water. I checked the hot water heater and found the pilot light was out. I tried to light it, but it would not stay lit. From past experience I figured the thermocouple as being bad. I hopped into the car for a trip to Home Depot were I found the Honeywell Universal Gas Thermocouple. It took less then five minutes to install. It came with several adapters for any installation situation. The 36-inch length was longer than I needed, but coiled up nicely out of the way. The pilot light was lit and soon I was enjoying a nice warm shower. October 7, 2006
Rated 1.0 out of 5.0 by Short Lifespan I feel like I just replaced this thermocoupler not even a year ago and now I am doing it again. I noticed someone else had the same issue with the 24" model. For the small price I don't care so much. But running out of hot water is a hassle. Not to mention the hassle of getting at my hot water heater to do the work. Yoga and contortions are not my thing. Shouldn't this product last more than a year??? October 24, 2013
Rated 4.0 out of 5.0 by This product worked on my gas boiler the pilot light started working again after I installed this thermocouple. I ordered it online and picked it up from the store. anyone who is having trouble with the pilot light on their gas boiler should replace this. easy to do but if you are not comfortable doing this, you can always contact a plumber.

Rated 5.0 out of 5.0 by Worked Great! Hot water tank has been giving me problems for a few weeks. Pilot light won't stay lit sometime will light but won't stay for more than a day. Anyway looked at buying a new water heater and then saw this ThermoCoupler. Thought that a $11 puchase was worth the chance that this was what was wrong. Was very easy to change just 2 screws and it worked. Water heater works great. Give this a try if you have the same symptoms. January 4, 2009
Rated 5.0 out of 5.0 by this is the one you want! Not the Rheem The Honeywell is straight forward replacement on both my steam furnace and water heater. The Rheem has to be rigged to stay in the pilot light position and it's a pain figuring it out. Unfortunately, HD only had the Rheem on this emergency run. Not sure if they don't carry the Honeywell anymore. Wish they did.... December 2, 2012
Rated 5.0 out of 5.0 by Great value My gas furnace pilot light would not stay lit when put it to on position.Replaced with this easy to do replacement and heat is on. October 30, 2011
