Thank you for the info. The expert response does not mention the thermocouple at all. Why then did the person from chat say to look at the thermocouple first? Also, If the outer air vent was never dirty on my water heater, as a suggested place to look, could the arrestor under the burner assembly become dirty anyway? I am confused about your second links purpose. Are you saying there is someone else I can ask this question to? I am just asking a question and appreciate the free advice, but I certainly want the response to be credible. How does the background of the qualified technician compare with the expert? Thank you.

Thank you for your question. I am sorry you are having a problem with the water heater. Usually when the pilot goes out for no reason I suspect the problem is a plugged air intake or flame arrestor. The flame arrestor is a fine ceramic filter in the bottom of the water heater. If it plugs up it stops the airflow and will cause the thermal cutoff to over heat and turn the gas off. I have provided you with the instructions for removing the burner and cleaning the flame arrestor. Make sure to use a brush and a vacuum to clean the flame arrestor. If the flame still goes out after cleaning the flame arrestor, I recommend replacing the thermocouple. The part number for the pilot assembly is 66001547 and can be ordered from our parts website Sears Parts Direct .

If you have any problems, please reply below with the details and I will be happy to assist you. Thank you for using Manage my life. Mark T.

Mark, Thank you for the response. Will do as you recommend and afterward post the results. Your link is multiple pages long, but I seem to be able to only print the first page. I tried manipulating the link but it still only shows as one page. If I reduce the size to fit on one page, the words are so small I cannot read them. Anything different you can do on your end to send as multiple pages? Also, if I have to replace the Pilot assembly, are any instructions available for this also? Thank you for your efforts, Richard

Thank you for the reply. I have broken the image down into 4 images and posted them below. You should be able to print them now. As for the pilot assembly, replacing it is not difficult. You just remove the screws and feed the lines through the front cover. I recommend taking a picture of the line routing before hand so you can route them in the same manner.

Feedback. It has been 2 weeks since I performed a thorough cleaning per your recommendations and the unit has performed flawlessly since. No new parts needed! It was shutting off up to 3 times a day previously. The advice was spot on with every detail described thoroughly. Thank you so much, I will recommend this site to everyone. I wasn't familiar with the rating star above and clicked wrongly, disregard the 2. Richard

Mark, I have been in the trades for 28 years, specializing in carpentry and multi tasking in everything else. That said it is hard to relate to an average homeowner. Common sense to one guy may only be because of training, formal or not. The lower cleaning was easy enough with the proper tools. I had very special attachments for my vacuum, and a long handle thin brush was needed. The inner burner assembly was more technical. An average joe may not even be certain how/where to unscrew the 3 connections at the valve area. The gasket and the glass door took more than average finessing to remove without damaging the gas lines. The inner assembly area is very tight. Burn residue was also on the bootom of the inner tank and needed to be vacuumed off before the lower disk. (Covered with a towel first) Reassembly was 'blind' trying to fit gas line into slot. The instructions were as good as they can be. My opinion is to properly clean both stages of this job requires above average skills and knowledge, seeing how gas lines are involved. Done wrong or carelessly could have great consequence.
