How to Fix a Heater That Won't Turn on in Cold Weather
When the temperature drops, a working heater becomes essential. A malfunctioning heater during cold months can make a home uncomfortable and even risky. It is common for heaters to face issues that impede their functions, such as faulty thermostats, clogged air filters, or ignition problems. Understanding these common issues and their solutions can save you from a chilly night and unnecessary stress.
In Whitefish Bay, where winters can be harsh, it is vital to have your heating system in top working condition. From checking your thermostat to inspecting the air filters, addressing these problems promptly ensures your heater stays reliable. Here, we delve into practical steps you can take to diagnose and fix a heater that will not turn on, ensuring your home remains warm and cozy throughout the cold season.
Check the Thermostat Settings
The thermostat is often the first place to check when a heater fails to start. Incorrect settings can lead to the heater not functioning as expected. Begin by ensuring the thermostat is set to “Heat” mode. It might sound simple, but incorrect mode settings are a frequent oversight. Also, verify that the temperature is set above the current room temperature.
Another aspect to consider is the thermostat’s placement. It should be away from heat sources like direct sunlight or appliances that radiate heat. If the placement is inappropriate, it might misread the home’s actual temperature, causing it to function inadequately.
In some cases, the thermostat might need recalibration. This involves adjusting the thermostat so that it correctly senses the temperature. Here are the steps to recalibrate your thermostat if needed:
1. Switch your thermostat to “off” and then back to “on” to reset it.
2. Adjust the temperature setting about 5 degrees higher than the room's current temperature.
3. Monitor the heater to see if it starts once the reset is complete.
Lastly, if your thermostat is battery-operated, ensure the batteries are functional. Weak batteries can cause the thermostat to malfunction, leading to heating issues.
Inspect and Replace Air Filters
Air filters play a crucial role in your heater's performance. Clogged or dirty filters can restrict airflow, causing the heater to overheat and shut down. Regularly inspecting these filters is imperative to maintain the heater's efficiency.
To check the air filters, follow these steps:
1. Locate the air filter compartment in your heating system, usually near the intake blower.
2. Remove the filter and check for dust and debris. Hold it up to the light; if you cannot see through it, it is time for a replacement.
3. Replace dirty filters with clean ones of the same size and type. Ensure they are installed right side up, as indicated on the filter frame.
Experts recommend replacing air filters every 1 to 3 months, depending on usage and the filter type. By maintaining clean filters, you ensure optimal heater performance and prolong its lifespan.
Examine the Furnace Pilot Light or Ignition System
Moving on to the furnace, the pilot light or ignition system could be your next stop if your heater is not kicking on. The pilot light is crucial as it initiates your heater’s combustion process. When this light is out, the furnace will not flame up, resulting in a lack of heat.
To check the pilot light, find its location on your furnace. Typically, it is accessible through a small door or panel. If it's off, try relighting it by following these steps:
1. Turn off the thermostat and ensure the furnace safety switch is on.
2. Locate the pilot light assembly. Switch it to the “off” position and wait a few minutes to clear any residual gas.
3. Turn the switch to “pilot” and, using a long match or lighter, ignite the pilot while holding down the gas reset lever.
4. Once lit, keep the lever down for about 30 seconds. Release it slowly and check if the pilot light remains on.
If the ignition system is electronic, listen for a clicking sound when turning the thermostat up. In cases where the pilot light does not stay lit, or there is no ignition sound, there might be an issue with the thermocouple or the igniter, which may require attention from technicians.
Check Power Supply and Circuit Breakers
A surprising number of issues stem from electrical problems. Ensure your heater receives power by first checking the power switch on the furnace. It often resembles a typical light switch and should be turned to “on.”
Next, inspect the circuit breakers. Go to your home's electrical panel and look for any tripped breakers. Here is what to do:
1. Locate the circuit breaker dedicated to the furnace.
2. If it’s tripped, switch it off, then back on to reset it.
3. Ensure there is no burning smell or unusual noises, as these are signs of electrical issues needing professional help.
