My boiler is suddenly throwing error code 52. Nothing has changed and everything else appears to be running right. I fear there may be a bigger issue.

I shut the boiler down for a bit and now the error 52 is gone and there is an error 72. My guess is the Controller is going bad, can anyone confirm that diagnosis?

    Sounds like your terminal strip may be loose, or your supply sensor has perished. Open the cover and make sure nothing has been in there chewing on wires.
