What to do if my Dunkirk DXL has no power between 4 & 1?
- BbradleymoralesAug 11, 2025
If your Dunkirk Boiler has no power between points 4 and 1, there are several potential causes. First, check if the limit switch is off and turn it on. A bad transformer could also be the problem, requiring replacement. Examine all connections for looseness or breakage, and tighten, repair, or replace them as needed. Also, check the fuse or circuit breaker and replace or reset it if necessary. Ensure the disconnect switch is on, and verify that the harness is properly plugged into the receptacle on the aquastat.
