When your Carrier heat pump model 25VNA8 displays the P5 error code, it’s likely indicating a low pressure or high voltage issue. You’ll want to check the electrical connections and wiring for damage or corrosion, and verify the outdoor unit’s coil temperature is within the recommended range.
If you’re not sure what to do next, inspect the board for signs of damage or corrosion, and check if the outside unit is properly licensed and meets specifications. Dig deeper to identify the root cause and resolve the issue before it affects your energy bills and unit performance.
Key Takeaways
- Verify the Carrier heat pump model 25VNA8 is compatible with the outdoor unit and check for any signs of damage or corrosion on the electrical connections.
- Check the voltage supply to the outdoor units, as low voltage can trigger the P5 error code, and inspect the outdoor unit’s coil temperature.
- Inspect the outdoor unit’s electrical components, such as capacitors and contactors, for wear or failure, and check the board for signs of damage or corrosion.
- Ensure the outdoor unit is properly licensed and meets specifications, and consult a licensed professional if unsure about the issue or troubleshooting steps.
- Identify the root cause of the P5 error code issue and follow the correct procedure to avoid further damaging the unit.
Understanding Error Codes and Symptoms
When troubleshooting your Carrier heat pump, understanding the error codes and symptoms is crucial to identifying the root cause of the issue.
You’ll want to familiarize yourself with the error codes, such as the P5 error code, which can indicate a low pressure or high voltage issue.
If you have a Carrier dual split AC or a Costway Mini Split, you’ll need to check the outdoor unit’s coil temperature and verify it’s within the recommended range.
Symptoms can include poor airflow, increased energy bills, or unusual noises from the split ac unit. Pay attention to any error codes displayed on the indoor unit, as they can provide valuable clues about the problem.

Diagnosis and Troubleshooting Steps
Your Carrier heat pump’s diagnosis begins with a thorough examination of the system. You should check the electrical connections and wiring for signs of damage or corrosion. A P5 error code often indicates an electrical fault, so verify the voltage supply to the outdoor units.
Low voltage can trigger this error, especially in multi-split AC units. Next, inspect the outdoor unit‘s electrical components, such as capacitors and contactors, for signs of wear or failure.
Outside Unit Model and Board Issue
If the P5 error code persists, it’s likely that the issue lies with the outside unit’s model or board.
You’ll need to verify the model number of your Carrier heat pump to confirm it’s compatible with the outside unit. Check your dual split or Costway Mini Split AC unit’s documentation for the correct model number.
If you’ve recently installed a new outside unit, confirm it’s properly licensed and meets Carrier’s specifications. A faulty or mismatched board can trigger the P5 error code, so inspect the board for any signs of damage or corrosion.
If you’re unsure about the issue, it’s recommended to consult a licensed professional for assistance. They can perform a thorough diagnosis and repair or replace the board as needed.
