Hi: Whirlpool Refrigerator Dual Evaporator WRF989SDAM00 I have been trying to get this working properly for a while now. Initially I determined a leak, found the leak on the RC evaporator and repaired it. Held 100 PSI nitrogen for a couple days, vacuum, and recharged with R134a 5.5 oz. Now it does this: On warm startup the refrigerator section cools down as it is supposed to as I understand. This unit cools one evaporator at a time. So the RC goes down to around 36.3F or so on my K-type thermometer at the RC fan output. That seems normal enough because the front panel setting is 37F. So then it goes to cool the freezer section. I see the freezer temp coming down on my second Ktype thermometer lead at the FC evaporator outlet, but does not ever get the freezer section cold enough. Front panel setting is 0F for the freezer. It goes down alright into the 40F and under area. But not lower. My suction pressure was a little too high seems to me. Would not go below 18 to 20 PSIG. I removed some refrigerant gas so it is drawing down to 6 to 10 PSIG now. But that is not the solution. It seems to me the compressor is just not drawing down enough to reduce the suction pressure to near 0 PSIG where it needs to be. So here's my question for now. What is the DC voltage into the compressor start inverter supposed to be doing during all this? The 120VAC into the compressor start inverter is solid. The 3-6 VDC into the inverter just stays at 3.4xx all the time, no matter what. Shouldn't this be varying to increase the compressor speed and therefore draw the suction pressure lower? What am I thinking wrong or missing here? I got this for nothing and as a project but would really like to troubleshoot it correctly. Thanks for any ideas/experience.
