If you own a Toshiba air conditioner with a heat mode and find that it’s not working, it can be quite frustrating. The heat mode is designed to provide warmth and comfort, so when it malfunctions, it’s important to understand the potential causes and how to fix them. In this article, we will explore the reasons why your Toshiba air conditioner’s heat mode may not be functioning properly and provide you with some troubleshooting steps to resolve the issue.
One of the common culprits for a malfunctioning heat mode is a faulty reversing valve. This valve plays a crucial role in changing the direction of the refrigerant flow, allowing the unit to produce hot air instead of cool air. Fixing or replacing the reversing valve requires professional assistance, so it’s best to reach out to a qualified technician for this type of repair. However, there are other potential causes to consider as well. Let’s explore some troubleshooting steps you can try in order to get your AC’s heat mode working again.
How To Fix A Toshiba Air Conditioner When The Heat Mode Doesn’t Work
Please note that the following steps are not listed in any particular order and can be performed based on your preference and comfort level.
- Inspect For Ice Formation
Check inside your air conditioner unit for the presence of ice. Ice accumulation can obstruct the airflow and prevent the heat mode from functioning correctly. To resolve this issue, follow these steps:
- Turn off the thermostat to prevent interference with the temperature change.
- Switch the AC to FAN mode to continuously blow air and help melt the ice.
- Examine the quality of the filter and clean or replace it if necessary.
- Allow the unit to dry completely after the ice has melted.
- Turn on the AC and try activating the heat mode again.
- Check The Circuit Breaker
Air conditioners consume a significant amount of electrical energy. Therefore, it’s essential to ensure that the circuit breaker can handle the power requirements, especially when operating in heat mode. If the circuit breaker is incompatible or insufficient for your AC unit, it may fail to activate the heat mode. Consult an electrician to evaluate the wiring and determine if any adjustments or upgrades are necessary.
- Reset The Remote
If you control your Toshiba air conditioner with a remote, check the batteries and buttons for any issues. Damaged batteries should be replaced, and loose buttons should be securely in place. Consult the user manual for instructions on resetting the remote. Additionally, ensure that there are no obstructions blocking the AC’s remote receptor. Toshiba offers advanced technology that allows you to control your AC unit via a mobile app. While this feature may not be supported on all mobile phones, you can follow these steps to set up your phone as a remote:
- Visit your mobile phone’s application store and search for the Toshiba virtual remote for AC.
- Read the app description to confirm compatibility with your phone.
- Download and install the app.
- Plug in your air conditioner and use the app to establish a connection with your phone.
- Test the app by controlling the AC’s functions through your phone.
- Fix The Thermostat
The thermostat plays a crucial role in communicating with your AC unit, especially when it comes to temperature changes. Ensure that your thermostat is programmed to respond to the heat mode setting. Sometimes, the thermostat may misinterpret the temperature when other heating devices are in operation, leading to inaccurate readings. Relocate the thermostat away from heat-sensitive areas like direct sunlight and place it in a central location or on an interior wall. If the thermostat continues to malfunction, seek assistance from a technician.
- Clean The Air Conditioner
Blocked airflow due to dust particles can impede the proper functioning of your AC in heat mode. To clean your air conditioner efficiently, follow these Steps using a vacuum cleaner:
- Run the AC in fan mode for a few minutes to help dislodge dirt and evaporate moisture.
- Turn off and unplug the AC unit.
- Set the vacuum cleaner to a moderate level.
- Open the AC cover.
- Thoroughly vacuum the filter, ensuring not to overheat the vacuum cleaner.
- Close the cover when finished.
- Plug in the AC and turn it on, then attempt to activate the heat mode.
- Regularly clean the AC to maintain optimal performance.
Determining When To Use The Heat Mode
To ensure an appropriate room temperature, it is advisable to activate the heat mode when the temperature drops below 55 degrees Fahrenheit. Temperatures below this threshold can pose health risks, particularly for individuals with respiratory issues. On the other hand, maintaining a warm room temperature can help reduce moisture and mold growth. It is important to keep the room temperature balanced and safe, ideally ranging from 68 to 74 degrees Fahrenheit.
Refrigerants Used By Toshiba Air Conditioners
Toshiba utilizes R-410a and R-32 refrigerants in their air conditioners. While R-410a has a higher Global Warming Potential (GWP) of 2,088, indicating a greater impact on the environment, R-32 boasts a lower GWP of 675, signifying higher energy efficiency. Toshiba plans to transition to using R-32 exclusively in their split AC units by the first quarter of 2025. This shift aims to significantly reduce carbon dioxide emissions and promote environmental sustainability.
