Diagnostics and servicing and repair, whether on a small appliance, large appliance such as (REFRIGERATOR , HEATING , AIR CONDITIONING , WASHER , DRYER , DISHWASHER , STOVE , OVEN , MICROWAVE , DISPOSAL ) is always about the same. It's a basic 1-2-3-4 approach.
1. Diagnose-Test the appliance to see what is wrong. Through this, we find the general symptoms (what is working and what isn't).
2. Pinpoint-Isolate the problem to the particular part that causes the trouble with your appliance.
3. Provide written estimate for your appliance repair.
4. Repair/Replace-after we've located the specific cause of the problem, we repair or replace the bad part(s) and put the appliance back into service.
