Fan Not Running on small fridge unit
Evening,
I have been asked to have a look at the fan not running on a small commercial fridge. Apparently all the plant is inside, and there is a controller externally on the wall.
I am more of a AC engineer than a fridge guy. Any ideas of where to start.
Obviously Ill check that voltage is there ect,
a plan of attack would be great, id usually stay well away but this is for a long standing customer, and i am looking at it for them as a favour.

Re: Fan Not Running on small fridge unit
evap fan not running on a coldroom- siezed- try spinning it with a screwdriver.
no power- possibly circuit breaker/fuse- door switch on door-link it out as a temporary
or evap coil temp too warm and coldrex panel holding it off due to too warm- could be anything- if youve got an ac background then its easier to work on a fridge than give a fridgie a city multi fault- personal unbiased opinion!

Re: Fan Not Running on small fridge unit
Hi willetts,
Please provide more information. What type of equipment is this? Is it a display unit or a walk in chiller. And which fan is not running the Evaporator or condenser?

Re: Fan Not Running on small fridge unit
its just familarising yourself with the set up- chances are your lucky and find it out on a pressure switch or a pool of oil round the blow off plug . then dig deeper to interogate -sometimes pulling ur hair out to try and unlock the temp cotroller to check diff, alarm parameters,defrosts.
all fun- until u get the walkin butchers freezer with a 10ft long coil with defrost heaters blown-shiverring whilst standing on dead animals -warmer than step ladders and quicker too.
