What do you do when your heat is frozen up?

If this is the condenser that is frozen, you have a problem with the defrost cycle. There are 2 things that need to be checked, the defrost sensor and the defrost control board. More than likely it is the defrost control board that is the problem and of course that is the more costly of the 2.

What is the function of the current sensing relay in an oil safety control scheme?

The electrical control panel for a refrigeration unit using single or three phase power. The control portion has an oil pressure safety switch, defrost timer, temperature controls and perhaps a refrigerant pressure control in conjunction with the normal internal overload circuit breakers for the compressor. After operation of the refrigeration unit for a period of time, a defrost control device cuts off the compressor and turns on the electric defrost heaters. As the evaporator coils are defrosted, defrost thermostats open the defrost heater supply circuits. When the current sensing relay senses that all the defrost heaters have been shut off via the defrost thermostats, a time delay relay will return the refrigeration unit to the normal refrigeration cycle. The same current sensing relay will prevent false triggering by the oil pressure safety switch if the compressor's internal overload circuit breaker opens
