* A water valve that is out of adjustment or restricted. Check the adjustment and the water supply.
* Insufficient air space around the unit. Ensure sufficient air space surrounds the unit (see “Specifications”).
* Refrigerant overcharge. Correct the refrigerant charge.

Why is the product from my Carrier C708 Freezer too soft?
J
John WalkerAug 26, 2025
If the product from your Carrier Freezer is too soft, consider the following possibilities:
* Insufficient air space around the unit. Allow 6” (152 mm) minimum clearance around both sides of the unit and place the back against a wall.
* Worn scraper blades. Replace the scraper blades.
* Dirty air-cooled condenser. Clean monthly.
* Outdated mix. Use fresh mix.
* Refrigerant shortage. Locate leak and repair.
* Product viscosity set too warm. Adjust product viscosity.
* Incorrect usage of the mix feed tube (C709/C717). Follow the correct feed tube procedures and use of the air orifice.
* Incorrect DBV setting. See “Checking and Setting Refrigeration Valves.”
