I installed a thermostat C-wire on my gas furnace, and may have overtightened and stripped the connector but the wires still seemed secure (thermostat C wire, and a/c condenser control wire). Working fine now, but what would happen if the wires came loose? Would it just stop powering the thermostat and starting the a/c condenser? Or could this cause damage? I prefer not to re-check or modify the connection because the furnace is very difficult to access.
