I need a new thermocouple for this 20+ year old furnace.  I can't seem to find the right part#, or a vendor to get it from.  Serial# on the unit is B10553L9B, if that helps narrow it down.  Any assistance would be MUCH appreciated...

I assume you can light the pilot but it won't stay lit? Who made the gas valve? Chances are it's a common brand and uses a 30 millivolt thermocouple. Take the old one out, measure for length and get a universal replacement.

I was just reading a blog about heating repair service Essex County NJ team, who is a professional contractor providing the service of all heating system's installation and maintenance. If you want you, can consult them to get the better advice regarding the furnace. They can help you in choosing the right thermostat for your old furnace. You can contact them if you feel comfortable with my advice or else can choose other options too.
