Hello everyone. Any help would be appreciated. I have a Magic Chef MCBR1010. I was having defrost issues so I did some research and replaced the following parts:

1. T-STAT
2. DEFROST TIMER
3. DEFROST THERMOSTAT
4. DEFROST HEATER

Now coils on the freezer half freeze. The bottom set of cables are great. The top half of the coils near the fan freeze and build up frost. I don't know what else to replace. Once again, thank you all in advance.
