Dunkirk VLT 75

Hello,

I have a Dunkirk VLT 075 that was installed on 2015. I had the Condensate Collector w/gasket & igniter replaced in September 2024. Now getting an "L" displayed in the 7th character position (manual only shows 6 character positions and the manual mentions nothing about an "L" indicator / error code). When "L" comes onto the screen, the unit immediately goes down to 1%. Lastly, I think I may have noticed a small amount of water around the nut of the Vent Temperature Sensor that screws into the condensate collector (as I am keeping an eye on that area). Question - Would it make sense to replace the Vent Temperature Sensor as a process of elimination since that part is roughly $50.00?

    The proper way to test the sensor is to measure its resistance vs. its temperature as given in the service manual.
