Troubleshooting Cadet Heaters: Fixing Common Issues

Cadet heaters are known for their reliability, but like any heating system, they can occasionally experience issues. Common problems include the heater not turning on, insufficient heat, or unusual noises during operation.

In many cases, you can fix these problems by checking the power supply. You can also reset the circuit or clean the unit to ensure good airflow. Regular maintenance and timely troubleshooting can keep your Cadet heater running smoothly and efficiently throughout the colder months.

• Check the power supply and reset the circuit breaker.
• Inspect and clean the heater to remove accumulated dust.
• Test and replace a faulty built-in thermostat if necessary.
• Ensure proper airflow by clearing any obstructions around the unit.

Heater Blowing Cold Air

Electric heaters blowing cold could be the result of many issues. These issues include:

• Manual reset tripped
• Loose wiring from the heating element
• Fan switch is "ON" but thermostat is set below room's temperature
• Air dispersal after shutting down the unit
• The heater unit is defective

Heater Won't Turn On OR Won't Stay On

A heater that won't turn on could be a result of high temperatures in the system. Abnormal temperatures are supposed to trigger the manual reset to avoid overheating. However, the manual reset can trip if the heater isn't properly cleaned or unobstructed.

A heater not staying on could also result from incorrect voltage wiring. For example, a 200V heater on a 120V circuit would not operate properly. If your wiring is good, your heater likely needs a repair or replacement.

For Com-Pak or Com-Pak Twin heaters, first try a power reset. If that doesn't work, inspect the unit for clogging and clean the heater if necessary. After resetting the heater should operate normally unless something more serious is going on.

Motor Running Slowly

Check that your heater is getting proper voltage supply and that the unit is clean. Incorrect voltage supply can cause the heater to underperform and can eventually lead to permanent damage. Clogged motors can rotate slowly which causes worse heater circulation.

Heater Overheating

If the heater keeps overheating, it may mean there is a bigger problem. This could be a broken heating element or wiring issues. You should get a professional to inspect and fix it. By staying proactive about these concerns, you can maintain a safe and efficient heating environment.

To keep your Cadet heater working well, regular cleaning and maintenance are important. This helps it perform better and last longer.

How often should I clean my Cadet heater?

Cadet suggests cleaning your heater at least once every 6 months. Luckily, cleaning your heater is a fairly straight forward process. Check Cadet Heat's 4 min guide on cleaning your heater below:

Accumulated dust and debris can obstruct airflow, leading to inefficiency and potential overheating. To keep your electric wall heater or baseboard heater functioning well, make it a habit to dust the exterior and clean the grills periodically.

Additionally, inspect filters and replace them as needed to enhance air quality and heating efficiency. Placing the heater in an unobstructed wall space promotes proper airflow.

A problem with the wall or built-in thermostat can greatly affect how well your Cadet heater works. This may cause uneven heating or even make it stop working completely.

Common issues include inaccurate temperature readings, failure to respond to adjustments, or cycling on and off frequently. Malfunctions can happen for the following reasons:

• Broken thermostat sensor
• Wiring problems
• Outside factors like drafts or poor placements.

If you use a digital thermostat and your wall heater cycles on and off (every 15 seconds), then it's possible you need to update the thermostat settings.

Every thermostat is different, so it's important to read the owner's guide for specific instructions.

If you think there is a problem, test the built-in thermostat. If needed, talk to a professional. They can inspect it and suggest replacements. This will help your electric heater system work well.

It's important to follow the manufacturer's instructions for installation and operation. This includes using the right electrical supply. Always keep the area around the heater clear of flammable materials, including curtains, furniture, and paper.

Also, think about putting a smoke detector and a carbon monoxide detector near the heater. In case of fire or gas leak, the detectors can alert you to danger quickly.

By following these safety steps, you can enjoy warmth without risking your safety.

• Regular Inspections: Check for damage, like frayed wires or cracks.
• Clear Surroundings: Keep the area around the heater free of flammable items.
• Follow Guidelines: Adhere to the manufacturer’s installation and operation instructions.
• Install Detectors: Use smoke and carbon monoxide detectors nearby to keep you safe.
• Educate Yourself: Read and understand safe operation procedures listed on the manual.
