Customer Questions and Answers for Relay And Overload Kit by Frigidaire

Hello Rob, With the new relay and overload assembly the capacitor is not required.

Hello Jeff, You need to check the voltage to the red line and make sure it is 120Vac. Also, I would check the new start device to make sure it is good. Do this by shaking it. If it rattles, it's bad. If not, and the voltage is good, you may have to replace the capacitor 218909902. The capacitor should be wired to both sides of the start relay. One wire to each side.

Hello Jeff, Now with the wiring diagram I can tell you with confidence, the red wire is hot, and the white wire is neutral. The relay has two sides and if you look closely at it you can see that the two terminals on each side are actually connected so even though there are four terminals, it is actually two points in electrical terms. In light of this, the two wires from the capacitor connect to each side. The polarity does not matter in this instance, but one wire to each side. And yes, red is hot and it connects to the overload.

Hello Jeff, N stands for neutral and L stands for line or hot wire. Without the model number, I can't pull up the wiring diagram so I can't tell you color to terminal and be sure as it would just be a guess. We don't like to guess as this costs the customer time and money. I can tell you with the information you have given that the hot wire will attach to the overload, (small white part with one terminal), and the neutral will hook to the side of the relay, (brown component that goes to the compressor after the overload goes on), that has two terminals. The capacitor will have one wire go to one side of the relay and the other wire to the opposite side of the relay.

Hello Juan. No, based on the information you provided, you will need to order and replace the relay overload kit 12002794 on the unit. This is the 2 wire relay starter instead of the 3 wire starter.

Hi Dan. You are on the right track because the complete compressor change out is a sealed system repair. Depending on the age/ price of the unit , a one time complete repair may be worth it. The cold comp. relay normally reads 4-5 ohms across the 2 terminals. If it rattles then it is definitely bad. Relay kit part # 5304410951. Compressor: The relay starts the compressor for operation. The relay WR07X26749 has a coil in it that is connected in series with the "run" winding in the compressor. When the power is applied, the compressor draws a high current as it is in a "stalled" state. This current is high enough to "pull" the relay in, which connects the "start" winding. This is connected through the capacitor which gives the start winding a "leading" state in electrical terms, which sets the motor rotating. As the motor speeds up, the current drops and is no longer sufficient to hold the relay up, and the motor continues to run without the "start" winding.. The neutral, or cold side of the motor is connected via a small thermal breaker which cuts the motor off if it doesn't start, until the breaker cools down, then it has another go at starting. This is the buzz and "Click" noise you sometimes hear if you turn your fridge off for a short period and then back on. The compressor often wont start if the discharge pressure is too much greater than the suction. Some compressors have a "run" capacitor as well which remains connected to give the motor a higher torque, both for starting and running states. All of this only takes a split second. Thank You.

Hello Tom. Yes, 5304410951 is the correct kit. You will install the white overload on the single post and the relay goes onto the double post. Then, look at the old part and the wire going to the single post, install it onto the overload. The wire going to the relay installs on the same numbers on the new realy. If you look at the old relay, it has numbers by the holes that the post goes through. You will match those numbers and wires up to the new relay. Hope this helps.
