E: System Runs, Box Temperature Too Low:
1 | Thermostat setting | Rotate thermostat knob to a lower |
|
| number. |
2 | Thermostat type | Check that you are using a refrigerator |
|
| thermostat (0028) for a refrigerator |
|
| application. |
3 | Faulty thermostat | If system is running continuously & |
|
| box temperatures are too low with |
|
| thermostat set on the lowest number, |
|
| first check for correct thermostat |
|
| connections at the Module, then remove |
|
| one connection. If compressor stops, |
|
| turn off breaker, replace connection & |
|
| then control system manually from the |
|
| breaker until the thermostat can be |
|
| replaced. |
4 | Holding plate | If you are using a holding plate |
|
| evaporator that is |
|
| application, it will absorb more heat |
|
| than that which enters the box through |
|
| the insulation, & so lowers the |
|
| temperature. Experiment by covering |
|
| some of the plate surface with |
|
| insulating material until you achieve |
|
| correct box temperatures. This method |
|
| will also increase |
5 Poor spillover system | If you are running the evaporator as a |
construction | freezer, & cooling an adjoining |
| refrigerator compartment with some |
| spillover air, there must be an adequate |
| thermal barrier between the two, & it |
| must be properly sealed to prevent |
| unwanted |
| refrigerator side should be controlled |
| either with |
| holes, or a thermostatically controlled |
| fan. Two apertures are necessary, one |
| high & one low for adequate air |
| circulation. |
