Temp Fluctuations

I am having some trouble with my Denver EF200 furnace. It has a Bartlett RTC-1000 control. The temperature readout drops 15 deg. F when the power to the elements comes on. It is very consistent.
I checked to see if the thermocouple extension wire was running close to a coil or high power line, but it is not.
Any ideas?
