Protect your A/C system's moisture control with the Four Seasons A/C Receiver Drier (manufacturer part number 33904). It installs as a direct-fit replacement for the 2004 and 2006-2023 Ford F-53 Motorhome Chassis, as well as the 2012-2021 Ford F-59 Commercial Stripped Chassis, restoring the drying and filtering stage on the high-pressure side of the air-conditioning loop.

  • Desiccant moisture control: the receiver drier holds desiccant that absorbs moisture from the circulating refrigerant, helping keep water out of the system.
  • Contaminant filtering: traps debris and particles that move through the refrigerant so they don't reach downstream components.
  • Liquid refrigerant storage: acts as a reservoir on the high-pressure liquid side, holding refrigerant for the expansion valve.

Over time a saturated desiccant or a restricted drier can leave moisture in the system and reduce cooling. If a failed receiver drier is the cause, this replaces it; it's also commonly replaced whenever the A/C system is opened for compressor or other component service. Diagnose the cause before replacing.

Frequently Asked Questions

What does an A/C receiver drier do?

It sits on the high-pressure side of the A/C system, using desiccant to absorb moisture from the refrigerant, filtering out contaminants, and storing liquid refrigerant for the expansion valve.

Which vehicles does the Four Seasons 33904 fit?

It's a direct-fit replacement for the 2004 and 2006-2023 Ford F-53 Motorhome Chassis and the 2012-2021 Ford F-59 Commercial Stripped Chassis. See the Buyer's Guide tab to confirm your vehicle.

What are signs the receiver drier may need replacing?

Reduced cooling and moisture-related issues in the A/C system can be signs. These symptoms have other causes, so diagnose the system before replacing this part.

Should I replace the drier when servicing the A/C system?

The receiver drier is commonly replaced whenever the A/C system is opened for compressor or other component service, since it can absorb moisture once exposed.

What interchange numbers does this part cover?

It cross-references 708360, 1C3Z19C836A, F81Z19C836AB, 603307, YF2517, YL215, 408910, A78903, 170308 and RD11157C. Its own manufacturer part number is 33904.
