Question: wil it replace a37c73u840
Document: This item saved me from replacing my whole water heater and consequently wasting more time, spending more money and cleaning the mess in my basement. It definitely worthed. My only concern was it wouldn't fit but it has proved to be almost identical with my broken one, which worked fine for about 7-8 years. It has been shipped very fast, I got it in about 4-5 days, and It took about 30 minutes to replace the old one, including draining the water from the reservoir.
fit perfectly on my boiler but unfortunately had to return it because my boiler was shot not just this thermostat
I noticed that a lot of these companies used the same controller, but sell the replacements at different prices. I have an AO Smith. And it works. Been going strong for a while now.
Exactly the ride control for a Reem water heater!Don't understand why it dident come with it in the first plase on the water heater!!! !
