Works with Honeywell controller

I'm just checking the sensor. I'm a homeowner making ends meet. If you are uncomfortable, hire a professional. I'm not a profi. Enter at your own risk. I bought this sensor for a Rheem water heater with a Honeywell controller. Bought water heater in 2016. As far as I know the sensor doesn't care what brand the water heater is. This only applies to the controller. That turns it off. Problem: No hot water. The LED will flash 7 times to indicate the combustible vapor sensor is blocked. Assuming…

Technical info

Update: There seem to be large manufacturing tolerances. I ordered three, one measured 11 kΩ, another 20 kΩ and a third 46 kΩ, at room temperature 80 degrees.

You can measure them first before replacing them, otherwise you may get another trigger right away. The functional specification for the Thermodisc/Emerson 25 VS sensor states that it sinks at 50k ohms. The…

Problem fixed Good fit water heater and parts

When I ordered this I was concerned it would not be an exact replacement as the back of mine had '25v' stamped on it but the online Description in this paragraph says nothing.

Replacing an old one is very simple: disconnect the water heater from all electrical connections, remove the metal plate protecting…

Pros
  • Excellent overall performance
Cons
  • Not all will fit

Raven comes to the rescue. hot water restored.

Let me start with the words THIS WORKS! This is important because at 11pm on a Thursday (No less than Memorial Day) my daughter found the water heater had stopped working with difficulty. I had to rinse with cold water from the tap. I diagnosed the problem and ordered the part from Revain by midnight for expedited delivery on Saturday. Friday, with no hot water, wasn't great for the whole family. The spare part came on Saturday, installed and viola! Hot water. My Richmond water heater, which is

Pros
