The MAC 7 is an older Kolpak controller found on walk-in systems such as the PC099T2 and the PCL249LOP. Its service menu is protected by a password, so setting changes are a technician job. These systems are old, but some are still cooling walk-ins in kitchens.
On a MAC 7 system we start with the basics: the condenser, the door seal and the coil. Then we check the controller, its sensors and the defrost. Replacement parts for older controls are scarce, so we find out what can be sourced before giving you a number.
When repairing an old system would cost more than it returns, we say so and compare that against a new controller or a new system. The number is on paper before we touch anything.

Frequently. We examine the controller, the sensors and the refrigeration side, then give you our honest view on repairing versus moving to a newer control.
Can I change the settings on the MAC 7 myself?
The service menu is password-protected, so settings are a technician job. Tell us what the box is doing and we check the settings. That is a technician task on this control.
What if parts are hard to find?
Before quoting, we find out whether the part can be sourced. If it cannot, we lay out the alternatives, including a new control, ahead of any spending. Quotes are in writing first.
