Why Boilers in Canton, OH, Short-Cycle

December 12, 2022

Does the boiler in your Canton, OH, home short-cycle? This happens when you turn the boiler on and it immediately turns itself off. Here’s why boilers short-cycle and how to fix the problem:

Water Pressure Out of Balance

Normal water pressure for a boiler is between 1 to 2 bars. Check this by viewing the pressure gauge on the front of the boiler. If the pressure isn’t 1 to 2 bars, that’s possibly causing the short cycle.

The boiler turns itself off when the water pressure is incorrect. Low pressure can mean there’s a water leak somewhere in your system. High pressure usually means someone added too much water when filling the boiler. Faulty parts could also cause this problem.

Check the water pressure gauge on your boiler. Contact an HVAC professional for assistance if the pressure is too high or too low.

Faulty Valve

Boilers will shut down if the temperature control valve is faulty. This valve regulates the temperature of the water in the boiler. Water that’s too hot causes leaks, so the boiler shuts itself off to prevent overheating.

Inadequate Fuel Supply

Boilers will short-cycle if they don’t get enough fuel. If it’s gas, also check to see if other gas appliances are performing well. In this case, you’ll call your energy supplier to check for fuel supply problems.

Dealing with the fuel supply should solve the problem. If the boiler continues to short-cycle, contact an HVAC technician for maintenance.

Faulty Water Pump

A faulty water pump has a problem moving water through the system. The boiler is likely to shut off to prevent itself from overheating. If this is the case, you need to get a service technician to check your water pump.
