I have checked the transformer and fuse within the furnace itself. I am getting 24V out of the furnace and into the EIM module, however I'm only reading 8.7 volts at the wires running out to the thermostat itself (3 wire run from EIM to thermostat)
Customer reply replied 2 years ago
I can jumper the red and white within the EIM to get the furnace to fire, but I can't seem to figure out why I'm not getting the screen to power up

Hello and thanks for using this service, if you have been waiting do not worry or get upset I am just one of the techs on here and I try to get to as many customers as I can and I just picked up your question now.

You may have blown the low voltage fuse on the board in the furnace. If you have a wire connected to the C terminal on the thermostat, go to the furnace and remove the panels. Gain access to the board where all the wires attach. Locate the slot fuse on the board...CLICK HERE...if your fuse is good and you only have 8 volts from there check the wiring to the thermostat you may have a break or you may just have a defective thermostat.
