This is the OEM factory-specified fan blower control board for the Carrier PF4MNA036T00AAAA air handler. The control board serves as the command center for all blower motor operations — managing startup sequencing, fan speed staging, and the integrated time delay relay that governs how long the blower continues to run after a heating or cooling call ends. When this board fails, you may notice the blower fan refusing to start, running continuously without stopping, or delivering uneven airflow and inconsistent temperatures throughout the home. In some cases, a failed board causes the entire air handler to go non-responsive.
Compatibility: Direct OEM replacement for Carrier model PF4MNA036T00AAAA air handlers. Also cross-references part numbers CEPL130541-01, 1171734, 103972, and 122621 for applicable Carrier, Bryant, and Payne air handler platforms. Always verify your existing board's part number against your unit's data plate before ordering. Need help confirming fitment?
