  Michael AcostaAug 7, 2025
  If your Cleaver-Brooks burner isn't starting, begin by checking and closing the main disconnect switch. Then, replace any blown control circuit fuses. Repair any loose or broken electrical connections. Reset the program relay safety switch. Inspect limit settings and ensure parameters are met. Reduce pressure or temperature to the appropriate setting if it's too high. Refill the water to the required level if it's low. Adjust fuel pressure as necessary to be within the settings of low and high-pressure switches. Finally, ensure the fuel valve auxiliary switch is closed.

  Shawn PhillipsAug 27, 2025
  If your Cleaver-Brooks burner has a pilot flame but no main flame, adjust the pilot flame to the proper size if it's insufficient. Open the manual gas cock if it's closed. Repair or replace the main gas valve if it's inoperative. Repair or replace the gas pressure regulator if it's inoperative. Ensure the oil supply is unobstructed and valves are open if the oil supply is cut off. Repair or replace the supply pump if it's inoperative. Refill the fuel supply if there is no fuel. Repair or replace the main oil valve if it's inoperative. Clean or replace the flame detector or sight tube if the flame detector is defective, sight tube is obstructed, or lens is dirty. Restore voltage to the main fuel valve circuit if there is insufficient or no voltage at the main fuel valve circuit terminal.

What to do if Cleaver-Brooks Profire E Burner shuts down during firing?
- C
  Curtis WellsNov 2, 2025
  If the Cleaver-Brooks burner shuts down during firing, there are several potential causes. First, check for a loss or stoppage of fuel supply and restore it. Inspect for a defective fuel valve or loose electrical connections, and repair or secure them. Test and replace the flame detector if it's weak or defective. Clean the scanner lens and clear the sight tube if they are dirty. If the programmer lockout switch hasn't tripped, inspect the limit circuit and reset any opened safety controls. If the programmer lockout switch has tripped, inspect the fuel lines and valves to ensure they are functioning. Also, check for open circuits in the running interlock and secure any that are found. Investigate and remedy the cause of flame failure. Adjust the air/fuel ratio correctly if it's improper. S...

- M
  Mercedes CarrilloNov 11, 2025
  If your Cleaver-Brooks burner has no ignition, start by inspecting and repairing the electrode grounding or porcelain if there's a lack of spark. Adjust the electrode to the proper settings if they are improper. Secure or replace the ignition cable if the terminal is loose or the cable is shorted. Replace the ignition transformer if it's inoperative. Check and restore voltage to the pilot ignition circuit if there is insufficient or no voltage at the pilot ignition circuit terminal. Ensure gas pressure is sufficient and replace or repair as needed if there is a lack of fuel. Check and close the low-fire switch if it's open in the low-fire proving circuit. Inspect and restore damper motor operation if the damper motor is not closed. Free any bindings in the damper system if the damper is ja...
