How to Reset Your Bosch Air Conditioner: A Comprehensive Guide

If your Bosch air conditioner is not functioning correctly, resetting the unit can often resolve common issues. This comprehensive guide will walk you through the step-by-step process of resetting your Bosch AC, providing advanced details and technical specifications to ensure a successful reset.

Locating the Reset Button

The reset button on your Bosch air conditioner is typically small and red, situated on or near the unit. The exact location may vary depending on the model, so it’s essential to consult your owner’s manual if you have trouble finding it.

Outdoor Unit Reset Button Location

For most Bosch air conditioning units, the reset button is located on the outdoor unit. This is the larger unit that houses the compressor and condenser coil. The reset button is often found on the side or top of the outdoor unit, sometimes behind a small access panel.

Indoor Unit Reset Button Location

Some Bosch air conditioners may have the reset button located on the indoor unit, which is the part that circulates the air inside your home. This is more common in ductless mini-split systems. The reset button can be found on the control panel or near the air intake vents.

Resetting the Bosch Air Conditioner

Once you’ve located the reset button, follow these steps to reset your Bosch air conditioner:

  1. Power Down the AC Unit: Begin by turning off the circuit breaker that supplies power to your air conditioning unit at the main electrical panel. Additionally, turn off the power switch on the outdoor unit.
  2. Wait for Capacitor Discharge: Allow the unit to sit for at least 30 minutes to ensure any accumulated electrostatic charge in the capacitors has fully dissipated. This waiting period is crucial for safety and to prevent potential damage to the unit’s internal components.
  3. Locate and Press the Reset Button: Identify the small, red reset button on your Bosch air conditioner. Press and hold the button for 3 to 5 seconds, then release it. This action will reset the unit’s internal systems.
  4. Restore Power to the AC: Flip the circuit breaker back to the “on” position at the main electrical panel. Then, turn the power switch on the outdoor unit back to the “on” position.
  5. Adjust the Thermostat: Set your thermostat to “cool” mode and adjust the temperature setting to a few degrees lower than the current indoor temperature. This will signal the air conditioner to begin cooling your home.
  6. Verify Proper Operation: After a brief delay, your Bosch air conditioner should start up and begin cooling the air. Monitor the unit’s performance to ensure it is functioning correctly.

Advanced Troubleshooting

If the reset process does not resolve the issue with your Bosch air conditioner, there may be more complex underlying problems. In such cases, it’s recommended to consult a qualified HVAC technician for further diagnosis and repair.

Common Issues Resolved by Resetting

  • Protection Circuit Breaker Tripped: The reset button can help restore the AC’s internal protection circuit breaker, which may have been triggered due to an electrical overload or other issue.
  • Thermostat Errors: Resetting the air conditioner can sometimes clear any software or communication errors between the thermostat and the AC unit.
  • Refrigerant Imbalance: In some cases, a reset can help rebalance the refrigerant levels within the system, resolving issues like the AC blowing warm air.

Safety Considerations

Before attempting to reset your Bosch air conditioner, ensure that all power to the unit is turned off. This includes both the circuit breaker at the main electrical panel and the power switch on the outdoor unit. Failure to do so can result in serious injury or damage to the equipment.

Additionally, be cautious when accessing the reset button, as some models may have sharp edges or other hazards near the button’s location. It’s always best to exercise caution and use appropriate personal protective equipment (PPE) when working on any HVAC equipment.


By following the step-by-step instructions and adhering to the advanced technical details provided in this guide, you can effectively reset your Bosch air conditioner and troubleshoot common issues. Remember to always prioritize safety and, if the reset does not resolve the problem, don’t hesitate to contact a qualified HVAC technician for further assistance.
