A regular research we get here at W.L. May is for the thermostat for a refrigerator. When we get a request for the thermostat in a refrigerator, the first question is "cold control or defrost thermostat?" For the folks who want a cold control, we have a variety of OEM cold control thermostats in stock and can get many others that are less common.
A mistake some amatures make when diagnosing a low cooling problem is thinking the compressor is always at fault for low cooling issues. The compressor can be fine, at least for now, if you are leaking refrigerant. To determine refrigeration leaks there are a number of techniques used, Bubble soap solutions, infra red dyes and UV lights, and "sniffer" meters.
Our last item this week is one of those "sniffer" meters, UEI Test Equipment makes RLD10. This meter is sensitive to .5 oz per year R134A, R123, or R410A. The meter features a two position sensitivity selector allowing a user to zero in one the source of a leak by increasing the sensitivity. It also auto zeros when turned on and features an 18 1/2" long gooseneck probe.
