How To Turn Off Cadet Wall Heater [5 Methods]

Below are 5 of the most common ways to shut off your heater.

Use The Standby Function

Many Cadet wall heaters come with a standby function that allows you to turn off the heater without completely shutting it down.

To use this function, follow the steps below.

  1. Initiate the process by simultaneously pressing the "+" and "-" buttons on your heater's control panel.
  2. Proceed by pressing the "M" button four times. You'll notice that an icon on the display starts to blink, indicating the configuration of standby mode.
  3. Use the "+" or "-" buttons to toggle the standby function on and off. When enabled, the icon will blink quickly, indicating that standby mode is active.
  4. After your selection, the display blinks for six seconds before returning to the main screen, confirming standby function activation with a visible icon.

Power On/Off Button

Another way to turn off your Cadet Wall Heater is to use the power on/off switch.

Locate the power button on the front of the heater's lower portion. It is easily identifiable due to its red color and prominent placement.

For specific models, this button may also serve as a reset function, offering additional functionality beyond just powering off the heater.

Shut Off The Circuit Breaker

If you can't find the power button, you can shut off the circuit breaker that controls the heater's power.

To do this, locate the circuit breaker panel in your home and flip the switch that controls the heater's circuit to the off position.

Disconnect The Power

Another option is to disconnect the power directly from the heater.

You'll need to unplug the heater from its power source to do this. Depending on your specific heater model, this could be a wall outlet or a hardwired connection.

Turn Off The Thermostat

You can also opt to turn off the thermostat that controls it. This will prevent the heater from turning on even if power is still flowing to it.

Simply adjust the temperature to the lowest possible setting or turn it off completely.

Troubleshooting Cadet Wall Heater When It Won't Shut Off

If your Cadet wall heater doesn't shut off, it could be due to various reasons. Here's how you can troubleshoot them.

Faulty Thermostat

A malfunctioning thermostat can cause the heater to run continuously.

If the thermostat is not accurately sensing the room temperature, it may not signal the heater to shut off.

Consider checking and calibrating the thermostat or replacing it if necessary.

Malfunctioning Primary Controller

The primary controller is responsible for regulating the temperature of your Cadet wall heater.

If it is malfunctioning, it can cause the heater to stay on even when it's not needed.

You can try resetting the primary controller or replacing it entirely to troubleshoot this issue.

Damaged Circuit Breakers

Damaged or faulty circuit breakers can result in inconsistent power supply to the heater.

Inspect the circuit breaker panel and replace any damaged breakers to ensure proper electrical flow.

Faulty Water Checking System

For hydronic wall heaters that use water circulation for heating, a malfunction in the water-checking system could cause the heater to run continuously.

Check for any leaks, pump issues, or water pressure irregularities.

Temperature Sensor Is Burnt

If the temperature sensor in your Cadet wall heater is burnt, it will not be able to regulate the temperature in your room properly.

You can try resetting the temperature sensor or replacing it entirely.

Blown Wall Heater

In some cases, a blown internal component of the wall heater might be causing the continuous operation.

Inspect the heater for any visible signs of damage or burnt components, and consider seeking professional repair.

Dirty Heater

Dirt and debris can block the airflow and cause the heater to overheat.

Performing routine cleaning and maintenance can help prevent such problems.

Why Does My Cadet Wall Heater Turn On And Off?

Your Cadet wall heater cycles on and off due to its thermostat's operation, maintaining the set temperature.

When the room temperature drops below the desired level, the thermostat activates the heater, and it turns off once the target temperature is reached.

It can also result from an improperly placed thermostat that inaccurately senses temperature fluctuations, causing frequent on-off cycles.

Another reason is if improperly sized for the room.

An undersized heater struggles to maintain temperature, while an oversized one heats the room too quickly and shuts off prematurely.

Be sure to follow the manufacturer's instructions and guidelines when operating your heater.

Regular maintenance is important to keep your heater functioning properly.

Get your heater inspected and serviced by a professional at least once a year. This will help to ensure that your heater is working efficiently and safely.

By following these tips and guidelines, you can enjoy the warmth and comfort of your Cadet wall heater while keeping your home safe and energy-efficient.
