paragon defrost clock walk in freezer problem

[hvactech88]

working on a walk-in freezer with a heatcraft evap, both coils are iced up found the clock set to noon, its 6 oclock threw it into defrost manually, tested electric heaters all working fans turn off the way they should deiced coils completely with the help with using hot water to speed process up. Defrost clock set to 40 min defrost, but would come out of defrost before then before the 40 minutes. time clock motor is working and moving ahead, so trying to figure if it is was the clock got stuck or could the defrost termination kilxon be no good and throwing it out of defrost to soon.

1. Where is the termination mounted?
2. Were you getting power on X when it came out?

You're not describing a defrost timer problem. You're describing a defrost termination switch problem. Hvac and refrigeration are as related as riding a bicycle and driving a car. Good Luck

X2. I would like to add this walk in freezers should have more than once a day defrost.

the X terminal has nothing to do with number of defrosts.... it is for defrost termination

No problem. The way the op stated it sounds like the walk in one has once a day defrost. Most wlk frez have 3-4 a day.

I agree almost all have 3 to 4 a day....

Sounds like you tried to fix the problem before you diagnosed it. Don't be in such a hurry. Let the defrost cycle do what its supposed to. Wait and see what it does. It will tell you whats wrong.

[hvactech88]

what do you mean about the termination mounted talking about the klixon is mounted on the return bend of the back coil the evap has two coils with the fans in the center, i had 120v on x when it was out of defrost

[hvactech88]

Does it hold temp?
What kind of shape is the box in?
How often are they in and out?
