Problem resolved. I removed the relay, cleaned the contact, and reassembled the unit. The compressor fired right up. I found another resource which explained how to verify that the relay was operating correctly. Thanks.

There's a current relay starting circuit on top of the compressor. There's also a run capacitor nearby. I assume you have a meter (you said you tested the compressor). Either component malfunction will prevent operation, but if you hear a clicking noise at the compressor, then most likely the whole assembly (plastic box with relay and fuse) where the wires attach to the compressor has to be replaced. It runs less than $50. Buy it online from the manufacturer's parts house, This is a common problem with domestic refrigerators and freezers.
A freezer is great for storing additional food that may not fit in your fridge freezer. If your freezer stops working, it's important to be able to troubleshoot it quickly so that food waste is kept to a minimum. Keep the following tips in mind if your freezer stops working.
Inspect the Relay The relay is a component that helps power the compressor. It is housed in a plastic box with the motor terminals and the overload protector and is connected to the Compressor; the relay is the largest component in the box. Closely inspect the relay and make sure it is not burned out. The relay can also be tested using a multimeter. If you see any signs that the relay has shorted out, you'll will need to replace it. If the relay makes a rattling sound when shaken, this is also a sign that it has shorted out. Examine the Compressor The compressor is essential to the performance of your chest freezer. It is the motor that powers the entire cooling system and if your freezer has ceased to work, you need to check it. This unit is located at the back of the freezer and sits in plastic housing; it can be identified by its football shape. You can tell that the compressor is broken if your relay is fine or if you hear a light hum followed by a clicking sound and silence. If your freezer is relatively new, it might still be under warranty and you could get a replacement compressor for free. If not, your compressor will need to be replaced by a professional. Investigate the Thermostat The fact that your chest freezer is not working could be down to the thermostat. This is the unit that regulates the temperature inside the freezer. To test your thermostat, remove the access panel on the side of the freezer. Next, use a screwdriver to remove the actual thermostat from the inside wall but do not disconnect the tube that runs from the unit into the freezer. Set the range scale on Rx1 on your multimeter to test for continuity. If your multi-tester reads continuity, your freezer problem lies in another spot. If your multi-tester does not read continuity, it means your thermostat is not working and you will need to replace it. Remove the tube from the old thermostat and attach it to the new one. Screw the new unit into place on the freezer wall and make sure the tube is not coiled or kinked as this will prevent the new thermostat from working properly.
Compressor is bad the clicking noise is the Start Relay/Overload is kicking on and off. compressor is warm because it's trying to start but can't Frigidaire is known for bad compressors. I don't think the Start Relay/Overload is bad because the compressor gets warm.
See if you have 120 volts at the compressor if you do do you hear any clicking sound at compressor if not replace compressor Start Relay/Overload if you hear clicking sound the compressor may be bad or Start Relay/Overload the only way to know is to replace the compressor Start Relay/Overload. If you do not have 120 volts at the compressor jump out the thermostat you should have 120 volts at the compressor now if not you may have a defrost timer Prob. if this is shelf defrost unit check timer turn knob to see if it starts.
That is the overload protector on the compressor. Keep the door closed to preserve the cooling you have from the frozen food. Leave it unplugged for about an hour. Bang on the compressor with a rubber or wooden hammer then plug it back in. If it does not start you either need a new start relay or a compressor.
The thermostat may have shorted out so that it is no longer making contact to put power to the compressor. After drying out the components try bypassing the thermostat and see if it will start or make any sound whatsoever. If it does start and run with the thermostat bypassed replace the thermostat. 4-6 inches of water can also get to the relay on the compressor. Replacing the relay and over load assembly also be a good idea.
try replacing the relay/ overload you can buy a supco replacement there's 2 of them one covers 1/15 - 1/6 and the other covers1/3 - 1/4 its really easy to wire up and cost effective. any questions don't hesitate to contact by e-mail firstname.lastname@example.org
compressor is running overloaded possible problems bad relay/overload /capacitor dirty or clogged condensers if the unit uses a condenser fan suspect a bad fan. and defective thermostats are notorious for short cycling. id check the coils first and if dirty clean up maybe that can be the major problem.
