I have to unplug wait for the power light to stop flashing red multiple times before it will come on


When the TV does this, the RED LED on the front will blink. For digits 1-10 it will blink pause then repeat. For numbers with 2 digits it will blink the first digit slow and then second digit fast. So 25 would be 2 slow blinks followed by 5 fast blinks.

Carrier Gas Furnace runs fine randomly stops blowing LEDs flash


That blinking light may be the diagnostic light. Count the blinks next time it fails. Carrier units will have two different blinks depicting the error code such as one blink followed by a pause than 3 blinks giving you an error code of 13. Then look at the wiring diagram, it will have an error code chart telling you where to start with your diagnosis. You already know that if you remove the cover it erases the error code, so look thru the small window first.

Coleman outdoor furnace/AC blower speed too fast


You are right slow for heat and fast for A/C. Here are the blower speeds black is high blue is med. and red is low if you have orange it would be med low. Look on the control board and see what color wire is connected to heat and let me know if you have something other then control board. You can take the wire that is on park and swap them around. ken
