As a facilities manager, one of your primary concerns is keeping your rooftop unit functioning properly. When your rooftop unit is not heating, it can be a major disruption for your business. Fortunately, there are a few steps you can take to diagnose and correct the problem. In this blog, we will discuss what you should do when your rooftop unit is not heating.
Diagnosing the Issue
The first step in resolving a rooftop unit that isn’t heating is to diagnose the issue. Start by checking the thermostat to make sure it is set correctly. Then, check the condenser coil and make sure it is clear of any debris or obstructions. It is also a good idea to check the air filter to ensure it is not clogged with dirt or dust. If the air filter is clogged, replace it with a clean one.
Checking the Blower
The next step is to check the blower. Make sure that the blower fan is operational and that there is no debris or obstructions blocking the airflow. You can also check the blower belt to make sure it is in good condition. If the blower belt is worn or damaged, replace it with a new one. Finally, check the blower motor to make sure it is functioning properly.
Inspecting Electrical Components
Once you have checked the mechanical components of the unit, it is time to inspect the electrical components. Start by checking the circuit breaker to make sure it is not tripped. You can also check the wiring for any signs of damage or corrosion. Finally, check the safety switch to make sure it is functioning properly.
Troubleshooting the Issue
If you have checked all the components and the unit still is not heating, it is time to troubleshoot the issue. Start by checking the coil temperature. If it is too low, you may need to adjust the control settings. You can also check the refrigerant levels to make sure they are adequate. If the refrigerant levels are low, you may need to call in a professional to recharge the system.
Conclusion
When your rooftop unit is not heating, it can be a major disruption for your business. Fortunately, there are a few steps you can take to diagnose and correct the problem. Start by checking the thermostat and the condenser coil to ensure they are functioning properly. Then, check the blower fan and the blower belt for any signs of wear or damage. Finally, inspect the electrical components to make sure they are functioning properly. If all else fails, you may need to call in a professional to troubleshoot the issue.
