Why does my Carrier C708 shut off and produce a fault tone?
If your Carrier Freezer shuts off and produces a fault tone, it could be due to: * A fault alert. Check the fault screen in the operator’s menu. * Insufficient air space. Allow 6” (152 mm) minimum clearance around both sides of unit and place the back against a wall.
Why is the product from my Carrier C708 Freezer too soft?
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 * Outdated mix.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.”
How to fix a Carrier C708 Freezer with no operation in any mode?
If your Carrier Freezer isn't operating in any mode, check these potential causes: * The unit might be unplugged. Ensure it is plugged in. * The circuit breaker could be turned off, or the fuse might be blown. Turn on the circuit breaker or replace the fuse. * The power switch may be in the “OFF” position. Place the power switch in the “ON” position.
What causes high head pressure in a Carrier C708 Freezer?
High head pressure in your Carrier Freezer can be caused by: * A dirty condenser. Clean the condenser. * 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. * A faulty blower. Replace the blower.
Why is product not being fed into the freezing cylinder of my Carrier C708 Freezer?
If product isn't being fed into the freezing cylinder of your Carrier Freezer, it could be due to: * Inadequate mix in the hopper (mix out light is lit). Fill hopper with mix. * Air/mix pump incorrectly assembled (C708/C716). Assemble pump according to instructions in the Operator’s Manual. * Incorrect usage of the mix feed tube (C709/C717). Follow the correct feed tube procedures and use of the air orifice.
What causes the product from Carrier C708 Freezer to be too stiff?
If the product from your Carrier Freezer is too stiff, it may be because: * The product viscosity is set too cold. Adjust the product viscosity. * The air/mix pump is incorrectly assembled or malfunctioning (C708/C716). Re-assemble pump or replace faulty components.
Why is no product dispensed from my Carrier C708 Freezer when the draw valve is open and the machine is in “AUTO” mode?
If no product is dispensed from your Carrier Freezer when the draw valve is open and the machine is in “AUTO” mode, consider these possibilities: * The door spout is plugged. Break down the machine and dislodge the door spout clog. * The beater is rotating counterclockwise. Correct beater rotation to clockwise. * There is inadequate mix in the hopper (mix out light is lit). Fill hopper with mix.
Why does my Carrier Freezer operate for a long time?
If your Carrier Freezer operates for extended periods, it could be due to: * Worn scraper blades. Replace the scraper blades. * High overrun product (C708/C716). Check pump operation for correct air/mix ratio.
Why is the liquid line of my Carrier C708 Freezer hot?
If the liquid line in your Carrier Freezer is hot, it is likely due to a shortage of refrigerant. Repair the leak and recharge the system.
What to do if the mix in the hopper of Carrier C708 is too warm?
If the mix in the hopper of your Carrier Freezer is too warm: * The temperature is out of adjustment. Adjust hopper temperature. * The agitator is not installed. Install the agitator.
