How to fix Columbia CEGDID075D Boiler not heating enough?
- AAlexander MorrowAug 11, 2025
If your Columbia Boiler isn't heating properly, start by checking your thermostat. Ensure it's set above room temperature. If the thermostat isn't working, inspect and replace the batteries. Also, verify that the boiler is receiving electric power and that the power supply circuit is on. If the burner flame is yellow (not enough air) or blue and noisy (too much air), contact a service technician. If the radiators are not heating, inspect steam air vents for proper operation.
