Hi, Am working on goldline f70-625 (makeline). The top is not cooling at all. while the bottom compartments are all fine. Checked the condeser fan and is working, and filter clean. the pressure is ok, no leak. what might be the problem?
I get no search answers for the description you have given. Goldline comes up mostly tires, Makeline is a system to prep for making pizza's copyrighted by Domino's, And the model number comes up as paper, hobby, Goldline also comes up as a name of a masterbilt digital temp control
So harrison, if you could describe the case and find the Brand, It would help. Domino's used several brands if it is a pizza prep table including Delfield, Advantco, If it is a Pizza prep, check if it has air cooling to the top or plate cooling. If forced air check the evaporator fans and cover/ducts. Check for freeze up of the coil. Air flow is critical. Is the coil clean? Do all compartments have a pan in place? If not, it will not cool properly.
Lastly, if the top has a cold plate, it is the last thing in the refigerant lines to get liquid/ gas. Charge wieght is critical for it to function as intended. Measure your tail coil temp. Should be below 35F late cycle. If not it is undercharged.
