Question about Refrigerators
Not sure what you need to do so I'll give you some basic info. The main thermostat is the on/off switch for the complete refrigerator and sends power to all components. The defrost timer is in the circuit between the compressor and defrost heater system. The clock motor on the time opens and closes 2 sets of contacts. The compressor contact are closed for approx 6 to 8 hrs and while they are closed the heater contacts are open. When the timer advances to the defrost cycle, the heater contacts close for about 30 to 45 minutes and at the same time the compressor contact will open. Hope this helps your project.

Why were those parts changed? Was the compressor cycling on overload at the time?
If so, you should have first replaced the relay/overload combination and the see what happened.

It could also have a bad defrost heater. The heater and defrost thermostat are located mounted on the evaporator coil and the timer is usually mounted in the control panel with the control thermostat or in the compressor compartment.

Where did you get the new timer and what is the part number? It is possible you have a defective defrost timer even if new but the most likely problem is you have a universal timer and have the detachable wires for the clock portion and going to the wrong terminal or a wire is not seating properly over the four tabs for its power source. Your refrigerator uses a WR9X502 Defrost Timer
