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, but are not limited to, the heater:

• Not turning ON
• Supplying Insufficient Heat
• Making unusual noises during operation

In many cases, these problems have simple solutions. Common fixes to Cadet Heater issues include doing one or more of the following:

• Checking the Power Supply – Simple checks, like confirming that you plugged in the unit or that there is loose wiring, could be the answer.
• Resetting the Circuit Breaker – A ground fault can trip your breaker and stop power to prevent electrical fires; resetting the breaker can restore it!
• Inspect and Clean the Heater – Removing excess dust can ensure operation and improve airflow
• Clear Obstructions Around the Unit – Allows continuous airflow and prevents choking the unit
• Test and/or Replace a Faulty Thermostat – Faulty equipment can stop your unit from receiving signals to turn on

Sometimes, the problem one is facing is more than just a loose plug or some accumulated dust blocking the airflow. In that case, here are some pointers on where to find the solution for various issues.

Heater Blowing Cold Air

Electric heaters blowing cold could be the result of many issues. These 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.
• Incorrect Voltage Wiring - A heater not staying on could result from incorrect voltage wiring. For example, a 200V heater on a 120V circuit would not operate properly. If your wiring is correct, it is possible your heater needs to be repaired or replaced.

*For Com-Pak or Com-Pak Twin heaters, try a power reset first. If the issue persists, inspect and clean the heater to remove dust buildup and potential clogs. After resetting, the heater should operate normally unless something more serious is going on.

Motor Running Slowly

If you notice your unit’s motor is stalling or isn’t moving as fast as usual, you can:

• Check the Voltage Supply- Incorrect voltage supply can cause the heater to underperform and can eventually lead to permanent damage.
• Clean the Unit - Clogged motors rotate slowly, which negatively impacts 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 straightforward 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 grilles 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 a 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 placement

If you use a digital thermostat and your wall heater cycles on and off (every 15 seconds), then you may 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.

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

In short, you can enjoy warmth without risking your safety by:

• Performing Inspections: Check for damage, like frayed wires or cracks.
• Clearing Surroundings: Keep the area around your heater free of flammable items
• Following Guidelines: Adhere to ALL manufacturer's installation and operation instructions.
• Installing Detectors: Smoke and carbon monoxide detectors keep you safe!
• Educating Yourself: Read and understand safe operation procedures listed on the manual.
