To Next PageTo Next PageWhy is my Rapid Air Handlers unit experiencing burner lockout?
If your Rapid Air Handlers unit experiences a burner lockout, it's likely due to a failure to ignite the pilot or main flame, or a flame control failure. To address this, reset the flame control module at the unit. Observe the unit to see at which step the lockout condition occurs.
How to fix Rapid 2005 when optional damper does not open?
If the damper in your Rapid Air Handlers unit isn't opening, first check for any obstructions. Make sure the linkage is tight and secure. Verify that there is 120 V at terminal 3B. If these steps don't resolve the issue, replace the damper actuator.
What to do if Rapid 2005 Air Handlers fan switch is on, but there is no power?
If the fan switch is on but there's no power on terminals 3 / 3A in your Rapid Air Handlers unit, check the wiring between the remote panel and the air handler. If necessary, replace the switch.
What to do if Rapid 2005 motor does not operate?
If the motor in your Rapid Air Handlers unit isn't working, there are several potential causes. First, ensure the main disconnect switch is turned ON. If that's not the issue, check for blown fuses in the disconnect and replace them if necessary. Also, inspect the control transformer for blown fuses or a tripped breaker, replacing fuses or resetting the breaker with the disconnect OFF. If equipped with a cool-down timer TD4, and it doesn't reset with power on 3A, consider replacing the TD4 timer. If the motor starter (contactor) doesn't operate with power on terminals 3D and 2, replace the starter. Finally, if the motor overload is tripped, reset it, check for the proper FLA setting, and replace the overload if needed. For tripped motor overload, also check and tighten screws on heater pac...
