almost like clock work , every 4 months the pilot will not light , replace TC , good to go another 4 months
Replaced gas valve 3 years ago , same problem
What in the world could it be ? I use the standard Honeywell TC 36" you find anywhere
Pilot flame looks nice .... keeps it cherry red
What's your inlet pressure? What's up with that nasty room? Do you have adequate makeup air and no source of depressurization? What about the rest of the venting? Have you tested at the floor with a combustion analyzer to ensure its not suffocating by CO2 displacing the O2?
Next time your at the parts house check on the Husky thermocouples. I haven't had any issues with thermocouples sense I switched brands. There about three times the cost but well worth the money.
If it is keeping it cherry red, that may be a big part of the problem. Over heating a thermocouple can DRASTICALLY reduce its life, and "cherry red" is way to hot.Quote:

Outlet was 3.7 , didnt check inlet , dont have combustion analyzer , venting on its own flue out the roof
Nasty room is a utility room in a pizza joint beside 2 walk-ins , entrance is always open
That makes sense about the glowing cherry red being a problem. Its hitting halfway down the rod. Thats probly my issue.
Any other appliance I've seen its hitting the tip.
Hmmmmmmm
Im going back and make an adjustment !
If this one burns out im going to try a Husky
