Anyone who RECENTLY installed a Whirlpool residential model?

I had an issue where it appears that my newly installed side-by-side Whirlpool doesn't seem to like my MSW inverter. Twice, when running off the inverter I had a burning smell coming from the inside (evaporator) side of the fridge. The fridge was replaced with a new one and the same thing happened again. The cooling in the freezer and refrigerator has not been affected.

I don't think there is anything wrong with the inverter, since it handles the microwave and electronics with no problem. The place that installed it said that they had installed many of these units with a Xantrex Freedom MSW inverter identical to mine. They also said that mine is the second one recently that has had this problem, leading me to believe that Whirlpool may have made a minor circuit modification that can be causing this. I have searched out the source and found a roasted resistor on a small circuit board. The dealer said they found the same problem in the first one.

I have since ordered a Xantrex Freedom SW2012 to replace the MSW and plan to swap out.

The installer is the one most concerned, because he has several installed and is worried that mine is just the tip of the iceberg. He is committed to replacement labor for no cost.

Whirlpool says that they don't recommend residential units in RV's, although, they are well aware that Tiffin, alone, is buying 12 units per day for new installs.

After saying all this, I am looking for anyone else who has recentlyhad a Whirlpool installed and may be experiencing a burn smell, coming from inside the unit. I'm thinking they may have made a minor circuit change that may be causing this.
  • Do NOT use a MSW inverter on Whirlpool reefers. If you have to, use a 1000 watt PSW inverter dedicated to the reefer. In my opinion, it makes more sense to replace the big inverter with a PSW so you never have problems with any of your electronics, now or in the future. We installed a Magnum 2012 to replace the stock Xantrex 458 when we installed our Whirlpool three years ago and have been very happy with it. We also stopped burning up our B&D Infrawave counter top toaster oven (fourth one)!
  • what the inverter experts claim

    While a modified sine wave inverter can be used for a number of electronics. A pure sine wave inverter is preferred because the majority of electronic products and appliances that need to be plugged in work well with the standard power you receive from utilities as standard utility electricity is a pure sine wave. These electronic products were designed to work on a pure sine wave! With the increasing sensitivity of modern electronics and the exponential growth in technological advancements, more and more products require a true sine wave in order to operate effectively.
