Not sure about the age of your autoformer. Mine is only a couple years old.
This is from Hughes website:
At first we are tempted to say very ‘well’. But this may not be the answer you are looking for!
Autoformers are used in industries to stabilize voltage and lower the operating cost of equipment. The Autoformer has 5 windings: 2 primary and 3 secondary. All models have surge and spike protection. When the unit is in Automatic and the park or input voltage is 116 volts or below, the output is 10% over the input. When the input is over 118 volts, the output is 2% over the input.
The Autoformer DOES NOT take power from the park.
It does not affect the park or input voltage, or make electricity.
What it is doing is changing the voltage – amperage relationship, lowering the amperage and raising the voltage. Since appliances run better on higher voltage, lower amperage, less overall power is used from the park, and better service is enjoyed from your RV
An Autoformer running at full output (50amps) will use 1 amp, but will cause appliances to cycle more often and run cooler. This will use less total power from the park.
