Why Your Heater Keeps Shutting Down Too Soon

Delivering Quality Comfort to the Homes and Businesses of Hartford County and New Haven County

Heating problems in Hartford are serious business, especially in January with the kind of temperatures we've been experiencing this winter. If your heater keeps shutting off unexpectedly, it’s a big issue. A good repair technician will be able to hunt down the source of the problem and correct it for you, but the exact cause may vary.

Here are a few reasons why your heater keeps turning off:

  • Vent blockage: Heaters are usually equipped with a safety device designed to shut the unit off if the internal temperatures get too hot. This is to prevent damage to the unit and maintain certain safety levels in your home. If the heating vents are blocked, the safety feature will kick in and the heater will shut off until it has a chance to cool down: even if your home hasn't been heated yet.
  • The thermostat is faulty: A thermostat could misread the temperature due to a problem with its internal gauges. Or it could be poorly placed in your home: subjected to drafts or warm spots that don’t accurately reflect the internal temperature.
  • Electrical overload: If an electrical component inside the heater is overloaded, it could trigger the circuit breaker, cutting off power to the entire unit. If you have to keep resetting the breakers in order to make the heater function, this is likely the problem. A trained technician can isolate the problematic component and repair or replace it to restore functionality to your heater.

Understanding why your heater keeps shutting down too soon is the first step to solving the problem. The next comes with contacting a qualified Hartford heating technician like those at Dynamic Mechanical. Give us a call today to make an appointment. You’ll be glad that you did!

Troubleshooting Guide: When Your Heat Keeps Turning Off

Check the Thermostat: Ensure your thermostat is set to the desired temperature. Low batteries can also cause malfunctions—replace them if needed.

Inspect Air Filters: Dirty filters restrict airflow, leading to overheating. Replace or clean filters monthly to maintain efficient heat circulation.

Verify Pilot Light (Gas Furnace): If you have a gas furnace, confirm the pilot light is lit. If not, relight following the manufacturer's instructions.

Clear Vents and Registers: Blocked vents or registers can disrupt airflow. Ensure they're unobstructed for even heating distribution.

Check Circuit Breaker: A tripped circuit breaker may shut off your heating system. Reset it and see if the issue persists.

Inspect Ductwork: Leaks or blockages in the ductwork can hamper heat distribution. Examine for any visible issues or hire a professional for a thorough inspection.

Regular Maintenance: Schedule annual professional maintenance to prevent and address potential issues before they disrupt your heating system.
