Re: commercial fridge
What is it? A Williams, Foster
When door opens, warm air sweeps in, the temp will go up
Worse if its in hot kitchen, then if door left open coil will ice up as well
If ice in back, then wont reach design temp

Re: commercial fridge
OK, lets start with the obvious. does the evap fan run when you open the door and press the doorswitch? is there more than one fan? do they both run the same way? is the unit so full of veg that there is no airflow around the inside? what is the stat set for? what kind of defrost timer (if any) is fitted? look and think, double door fridges are toys. in short much more info required.

Re: commercial fridge
thanks for your replies i know it not a complicated system but i have never come across this before.i think it is a gram fridge but is rebadged as polar.both fans do run when you open the door and press the micro switch for that fan.they both run the same way.there is enough room in the fridge for airflow.the stat is set for 3 celcius.the query i have is this if i removed the door switch for the fans would this make any difference also the veg is stored in water could this also be a problem.it is in a chineese restaurant ambient is quite high not sure exactly what. could i fit a blower/air curtain above the doors connected to the door switch. any feedback much appreciated.

Re: commercial fridge
Have you checked the drain off the evap
there must be some sort of liquid on the back wall for ice to form.The primary function of the design engineer is to make things difficult for the fabricator and impossible for the serviceman.

Re: commercial fridge
Heres one. Tap the back of the cabinet from the outside where the ice is forming. Does the insulation sound ok??
I've heard of cabinets where there are hollow spots in the foam.
If there is get some space invader, drilla small hole and give it a blast. Then just pop a rivet in to seal the hole and wack a service lable on it.
