Hopefully their are not any chunks from the beer stuck somewhere in the system. Disassemble the faucet and keg coupler and inspect all parts for blockage. Be certain that their are not any blockages at the pressure inlet on the coupler. Inspect the fittings on the beer line as well. Clean all parts thoroughy. When you receive your new keg, place it in the kegbox ASAP and allow to aclimate. Attempt to adjust the box to 38 F liquid temperature using calibrated thermometer. Set pressure at 14 PSIG after checking pressure side for leaks. Keep us informed[8D]
