EDT11 Electronic Defrost Timer 120Vac

Defrost Time from 10 to 35 minutes and Defrost Frequency from 4 to 12 hours.
SUPCO®’s EDT Timer replaces most timers being used in today’s domestic refrigerators and freezers!

• Temperature Range: 32 °F – 135°F (0°C – 57°C)
• Humidity Range: 10 – 95% Non Condensing

• WARNING! To avoid possible electrical shock, which can cause death or serious injury, always disconnect power from the appliance before attempting any repairs or modifications.

Installation:

The EDT terminal configurations are similar to most original timers. In this case the EDT is a PLUG-IN-REPLACEMENT of the original timer.
However, always compare terminal designations of the EDT to the timer being replaced. The EDT terminal designations are listed below.

In the table the term “Timing Motor” is just a convention since the EDT is an electronic device and has no motor.
Some refrigerators such as GED^ do not incorporate connectors for a defrost timer hook-up. Each terminal is connected using a separate wire. In this case, very carefully bend terminals 2, 4, 3. Use needle-nose plier to hold the terminal while bending it with another plier.

Set-up:

After the EDT has been installed, and power has been restored to the equipment, the compressor cycle will be enabled. To advance to the defrost cycle, press and hold the button on the EDT for 30 – 60 seconds. The compressor should stop and the defrost circuit should activate. Holding the button will continually advance the defrost and run cycle. Power interruptions will not cause the EDT to recycle. The EDT will remember its position in the compressor cycle for at least 6 hours without power. If the EDT is in the defrost cycle when power is interrupted, the defrost cycle will start at the beginning when power is restored.
The EDT will directly replace all Whirlpool'” “Continuous Run” and “Cumulative Run” defrost timers as well as all other makes. The housing of the EDT has dimensions similar to ParagonTM universal defrost timers, including mounting holes. The “Defrost Frequency” is adjustable from 4 to 12 hours, and the “Defrost Time” is adjustable from 10 to 35 minutes. Adapter kits and mounting brackets are available when required.
The EDT will plug into the existing wiring harness in all but the following applications. Follow the specific installation instructions listed below in these cases.

Westinghouse’TM, Montgomery-Ward'” and Signature”‘ timer numbers such as: C42669, C56363 thru C56883, C460419 thru C714704, 2656D71H01 thru 2656D71H06 and 2660D93H02. Also, GE” model WR9X217, PhiIcon” 5833-027, Sears'”‘ 5586250 and Norge”‘ 12-4611. To install an EDT in these applications, an adapter kit (SUPCO®P/N WH3) will be required.
Using the SUPCO(R: P/N WH3, three wire adapter kit, attach the short jumper between terminals 3 and 4. Next, attach the three wire connector harness to the EDT. Attach harness leads to the same numbered original wiring terminals. The original ground lead (old terminal #3) must not be used. Tape or sleeve the end and secure it out of the way.

KELVINATORim, NORGETM AND DURACRESTm 4 TERMINAL MODELS
The EDT will replace many Kelvinatorm, Norge”‘ and ‘ Duracresr four terminal original defrost timer by using SUPC0-R’ P/N WH4, four wire adapter harness kit. Wiring will require connection of the harness leads to the same numbered original wiring terminals unless the model number is listed below. Any leads removed from original terminal “L” should be stripped and connected together using a wire nut. (Terminal L was a junction point and these leads must be reconnected to each other only.) The exceptions follow:
SOME KELVINATORTm AND DURACREST'” 4 TERMINAL MODELS
When replacing Kelvinator!” or Duracrest”” timer numbers G159148, K1227902, 1166601, 1222012, and Norge” 13-5699, the EDT will be installed with the same four wire adapter harness kit, but the wiring will be slightly different. Harness lead 2 is connected to No. 2 of the original wiring. Harness lead 1 is connected to No. 3, harness lead 4 is connected to No. 4, and harness lead 3 is connected to No. 1 of the original wiring.
SOME ADMIRAL'”, TAPPANim, HOTPOINT” AND NORGETM 5 TERMINAL MODELS
Following are some common five-terminal defrost timers. Admiral'” and Tappan!” timer numbers 23103-2 thru 24399-1 and 26308-2. HotpointTM timer numbers 123400 and WR9X5034 and Norge”” timer numbers 13-4243 thru 13-5423. In these applications, use SUPGY9No. WH4, four wire adapter harness kit if needed. The original wire from terminal No. 5 (if used) must be connected to terminal No. 4 of the EDT20 along with the original wire No. 4.
AMANAim, FRIGIDAIRETM, AND SOME MONTGOMERY-WARD'” AND NORGE”‘ 5 AND 6 TERMINAL MODELS
There are some other 5 or 6 lead timers in use. These are typically, Amanarm numbers C35250-1 thru C35655-7, Frigidaire” numbers 620524 thru 623773, 6540723 thru 6594595 and 7511697 thru 7546847. Also, Montgomery-Ward” numbers C48435 and 623772 thru 628518 and Norge” numbers 11-9481.
12-4609 and 12-9282. In these applications, use the SUPCO® No. WH4, four-wire adapter harness kit if needed. Wire harness lead 1 to No. 3 of the original wiring, lead 2 to No. 4, lead 3 to No. 1, and lead 4 to No. 2. Original wire No. 5 will not be used, it should be sleeved or taped and secured out of the way. Any wires that were on original terminal No. 6 should be stripped and connected together using a wire nut. (Terminal No. 6 was a junction point and these leads must be reconnected to each other only.)
NOTE: If SUPCO adapter kit WH3 or WI-M is specified above, please order separately. A mounting bracket may also be required depending on the installation. This may also be ordered separately. (SUPC0QcP/N MB1)
IMPORTANT! In all cases, exposed parts of the adapter wiring must be electrically insulated. Unused wires must be insulated and secured to prevent future pinching, cutting, or entanglement with fans or other moving parts.
During the installation, the “DEFROST FREQUENCY” (DF) and the “DEFROST TIME” (DT) must be set. Try to determine the correct settings by looking for information on the old timer, by cross reference material or service information on the specific unit being serviced. The actual settings are established by the refrigerator manufacturer and are based on the wattage of the defrost element and it’s physical location as well as several other factors and assumptions. If there is no information pertaining to the correct Settings to be used, follow the chart on pages 2 and 3. (Most models of the makes listed here, can be set as shown in the chart) This information is based on recent model information and is not intended to override manufacturer’s recommendations.
Part numbers and illustrations are intended solely for identification. Items offered for sale are not represented to be manufactured by the company that built the original model.
