Replacement door seal for walk in freezer
First, call Restaurant Parts and More (1-888-814-1110) and ask for Rick. He can help either get you the seal or have one custom made. I've used him for 15 years with great success. If you have model and serial, it would be even greater.
He can do the same for the heaters that go around the door frame.
Don't understand which "Line" you are referring to. In alot of cases, the drain on the drain pan is clogged. This causes water to overflow onto the floor. The drain can be clogged from trash getting into it. Most of the time, the drain heater is either not working or not ever installed. Water refreezes in drain line and causes the overflowing problem.
If this does not help, let me know. Clear up the "Line "question and maybe I can go alittle deeper into this. Read More At : Freezers...
