Question DetailsAsked on 3/9/2015

I just installed a 3 in 1 hard start relay on my fridge compressor warm fan running but still not cooling system?

How do I know if the compressor bad if it's warm or the condenser?

Assuming you have cleaned the airways around the fan and any lint on and around the compressor (without removing the insulation protecting the reefer from compressor heat), including cleaning the lint buildup off the coils (which provide the cooling for the refrigerant that makes the system work, and that the compressor is kicking on and actually running, if you turn the cold dial to the colder end and are not getting serious chilling in the freezer coil area (usually bottom panel) and cold air into the reefer part, then it is likely your refrigerant has leaked out and you need to Search the List under Appliance Repair - Large for a repair technician. Cost likely to be significant (couple to several hundred $) and may take several days for parts to come in if leak is in compressor or coil - so if an old reefer that might be on its last legs this might be time to consider a new one. Tough call, on sinking a few hundred $ into an older appliance which might then die of something else soon, but the older ones tend to keep going a lot longer than the new over-electronicized ones, so some people like me keep the old non-electronic appliances going as long as parts are available.

If compressor is not running at all, then cost likely in the $300-400+ range unless it is just a sensor or switch failure.

Unfortunately, you have sunk money into the hard start kit already, so you are sort of committed. Was this done by an appliance repairman ? Usually those kits are used only on older electrical systems to reduce the overloading of the wiring and light dimming when the compressor kicks on - it is quite likely its hard starting was due to overheating and the kit was not addressing the problem, if loss of coolant or dirty evaporator coils were the cause.
