How do I wire the defrost timer - where do I put the lead - on "1" or "2"?
And do I need to use the jumper wire?
If you have only 3 wires to connect to your timer then you would need to use the jumper between pins 3 and 4 and the loose terminal would go to terminal number 2. If it is a 4 wire connection then you will need to determine if the unit is a continuous run or a cumulative. If it is a continuous run then you would need to install the jumper wire on terminal 1 and if cumulative will be on terminal number 2.
How do you install this? I need to know what to do with the jumper wire.
Answer Hello Fuller. You will attach the wire to number 2 on the timer. The only way you will use the jumper is if your harness only has 3 wires. Then the jumper will got across terminals 3 and 4 of the timer.
Once the timer (4391974) is plugged in how long will it take for it to kick on?
Answer Hello Kim. The time varies. This is a 6 hour timer, but most are run by the run time of the compressor.
I have just bought a replacement 6 hour defrost timer. Which number does the lead go to? No.1 for continuous or no. 2 for cumulative?
Answer Hello Chuck,
This unit should have the lead connected to terminal 1. This allows the defrost timer motor to run continuously and defrost on a regular time schedule.
I have an Admiral Ref. and I was wondering what terminal do I place the black lead on? (Defrost Timer Part#4391974)
Answer Hello Mark,
You will put the black wire on terminal number 1. This is a continuious configuration as the unit calls for a defrost cycle every 6 hours.
