Maytag model msd2454GR* COIL FROZEN UP. FREEZER 0 deg. ref. 60 deg. Compressor running, fan above coil works. Why is the coils icing up? Thanks ,Gene.

Could be dirty coils.When was the last time they were cleaned? Could be low on refrigerant due to a leak. Could be the defrost heater or timer is not working. Check these other than refrigerant pressure( you have to be certified to check this) and report back
