Weak Propane Performance on Norcold N180.3X

tombeaux

We have been fortunate that our Norcold 3-way has worked well under frequent and heavy use on both shore power and propane. On the last two trips, it seems weaker on propane. When I light it, the indicator that is supposed to cross from white to green after a few minutes only travels to the line dividing the two colors. It is lit and there is heat coming out of the outside vent by the door, but I am wondering if there is some restriction somewhere. Any ideas? Photo attached to show where the indicator parks.

Mine also stays at the line dividing the colors, it has done that from the beginning but it works just fine
