Question: on a reliance 606 hot water heater, model # 640YORS which pilot assembly is used, 900531 or 900542?
Document: Just what it says - replacement for recent model water heater pilot assembly. No adapting, just order and replace. Long and detailed instructions, but given the hazards of replacing a natural gas device, its required and helpful.
The Reliance Water Heater #9003542Nat Gas Pilot Assembly worked perfect and was easy to install. I purchased the product through Amazon and they provide several vendors to select from. That gives you the opportunity  to order from the closest and the one that provides the best deal for you.
I needed to replace my pilot assembly on my water heater... And this was perfect for that! After I received the quick shipping (LOVE PRIME!) My hubby and son installed it in a matter of minutes and we were back in business with our hot water! Thanks Amazon for having it here for me to purchase! :o)
I have a Kenmore Power Miser 12 (Model Number 153331544).Its pilot assembly is part number 9003540 from Sears.This is an identical part / perfect fit for less than half the price!
This part is working just fine. I am just glad to have hot water again! I don't recommend Reliance water heaters for anyone.
This thing is almost exactly the same as what was in ourAO Smith model# GCV 40 100 water heater. Right down to the markings stamped on it (pretty much, anyway).The only thing wrong with the old one was the resistor wire hadcracked and was not making contact. That will effectively disablethe water heater, so that pilot light won't reliably stay lit.Multiple cleanings and fiddling with it before I discoveredthe cracked wire connection.
The part came next day as requested and in good order. The change out was quick and simple and my A.O. Smith water tank is again putting out hot water. Thanks to the review from the user that left his input on model GCVL 40 100 Tank I had the confidence it would work even though it was from a manufacturer other than A.O. Smith. And did I mention, it was less than half the cost ?
I bought this for its identical twin sold as a Kenmore. I installed it but after just a few days of use the pilot light would burn out constantly causing us to have to light the heater every time we needed hot water.
The old pilot assembly of our water heater is broken after 10 years' using.
Perfect match for my water heater, easy to install, well constructed, would recommend to anyone purchasing a replacement Pilot assembly.
Answer: yes
