A York 3 to 5 ton ZF rooftop uses one 24 in. direct-drive propeller fan on one 1/2 HP, 1090 RPM condenser fan motor, per York form 697890-YIM-C-0213 (ZF036 to ZF072, 60 Hz). The 6.5 to 12.5 ton Predator DH078 to DH150 line uses two 24 in. fans, with 1/3 HP motors on the DH078, DH090 and DH102 and 3/4 HP motors on the DH120 and DH150 (form 246646-YTG-C-0606). Match voltage, rotation and shaft to the motor nameplate before you order.
What condenser fan does a York 3 to 6 ton ZF rooftop use?
The physical data table in form 697890-YIM-C-0213 lists the condenser fan for the 3 to 5 ton models like this:
| Model | Fans | Diameter | Type / drive | Motor HP (each) | Motor RPM |
|---|---|---|---|---|---|
| ZF036 (3 ton) | 1 | 24 in. | Propeller, direct drive, 1 speed | 1/2 | 1090 |
| ZF048 (4 ton) | 1 | 24 in. | Propeller, direct drive, 1 speed | 1/2 | 1090 |
| ZF060 (5 ton) | 1 | 24 in. | Propeller, direct drive, 1 speed | 1/2 | 1090 |
The later ZF036 to ZF072 manual, form 5188244-YIM-B-1016, lists the same 24 in. fan and 1/2 HP motor. For the ZF072 it shows two motor types: 1100 RPM (ECM) on cooling-only and electric heat units, and 1090 RPM (PSC) on gas heat units. So a 6-ton unit may not take the same motor as a 3-ton. Check the nameplate.
What current does the condenser fan motor draw on a J03ZF to J05ZF?
For the J-code ZF line, the electrical data table (Table 7) in form 697946-JIM-C-0213 (J03ZF and up, 60 Hz) gives the outdoor fan motor full load amps, each:
| Models | Unit voltage | OD fan motor FLA (each) |
|---|---|---|
| J03, J04, J05 | 208-1-60, 230-1-60, 208-3-60, 230-3-60 | 2.3 A |
| J03, J04, J05 | 460-3-60 | 1.3 A |
| J03, J04 | 575-3-60 | 1.3 A |
The two condenser fan motors listed on the store's J03ZF page are titled as single-phase motors, one 230V and one 460V. Match the York part number and voltage on the old motor's nameplate, not just the unit voltage.
What condenser fans does a York Predator DH rooftop use?
Table 2 (DH physical data) in Predator technical guide 246646-YTG-C-0606 lists two condenser fans on every DH model:
| Model | Fans | Propeller diameter (each) | Motor HP (each) |
|---|---|---|---|
| DH078 (6.5 ton) | 2 | 24 in. | 1/3 |
| DH090 (7.5 ton) | 2 | 24 in. | 1/3 |
| DH102 (8.5 ton) | 2 | 24 in. | 1/3 |
| DH120 (10 ton) | 2 | 24 in. | 3/4 |
| DH150 (12.5 ton) | 2 | 24 in. | 3/4 |
The store's DH090 and DH120 pages list the fan blade, motor harness and motor mounts for these units, but not a condenser fan motor. Read the York part number off the old motor and send it to us.
When is the condenser fan supposed to be off?
Before you condemn a motor, make sure the control isn't holding it off. Form 697890-YIM-C-0213 says that when the high pressure switch, low pressure switch or freezestat opens during cooling, the unit control board shuts off the compressor, starts the anti-short cycle delay and stops the condenser fan. The compressor restarts after the delay if cooling is still called for.
The same manual describes a low ambient mode, enabled by a switch set at 45°F, in which the compressors run 10 minutes on and 5 minutes off while the indoor blower keeps running. So a fan that is not turning is not always a failed motor.
Our practical advice: on a direct-drive fan, check the blade and the mounts while the motor is out. A bent blade or a broken arm mount will kill a new motor's bearings.

Frequently Asked Questions
What HP is the condenser fan motor on a York ZF036 to ZF060?
York form 697890-YIM-C-0213 lists one 1/2 HP, 1090 RPM direct-drive motor turning one 24 in. propeller fan on the ZF036, ZF048 and ZF060.
How many condenser fans does a York Predator DH090 have?
Two. Technical guide 246646-YTG-C-0606 lists two 24 in. propeller fans with 1/3 HP motors on the DH078, DH090 and DH102, and 3/4 HP motors on the DH120 and DH150.
What amps should a York J03ZF condenser fan motor draw?
Table 7 of form 697946-JIM-C-0213 lists 2.3 A full load for each outdoor fan motor on 208/230V units and 1.3 A on 460V units.
Why did my York rooftop condenser fan stop while the blower kept running?
Per form 697890-YIM-C-0213, the control board stops the condenser fan when the high pressure switch, low pressure switch or freezestat opens, and restarts after the anti-short cycle delay. Check for a safety trip before replacing the motor.
