UT Controls Intermittent Pilot Ignition
« on: November 16, 2018, 12:49:31 AM »
I need to replace the pilot ignition module on my rooftop HVAC unit.
The original is marked 1003-600A Series. A separate tag on the module reads 1003-662A-1.
I find many replacement units that are the 1003-600A series, but have numbers like 1003-633A,
1003-665A, 1003-620A, etc. Are these interchangeable directly with the original?
Thanks  :-\
