1/ Is it plugged in? 2/ Is the switched on? 3/ Checked main fuse box? 4/ Still under warranty? If so call em up.

Try just using zone 1 for heat and cool..........

As stated, sounds like the transformer. This is normal, it's always sounded like that but now your REALLY listening!!

The yellow wire is the cooling wire, it goes to the "Y" terminal. The red wire is the hot 24 volt wire, it goes to the "R" terminal. The green wire is the blower or fan wire, it goes to the "G" terminal. The white wire is the furnace or heat wire, it goes to the "W" or "W1" terminal.

If your unit is shutting down due to the outdoor pressure switch. The main two problems are the outdoor fan is bad ( the blade is not turning at full speed or not at all, motor getting hot after running a while and shutting down) or the outdoor coil is dirty. The outdoor coil gets a lot of dirt and debris impacted in the finn area. You need to disconnect all power and wash it out with a water hose. You must wash it the opposite flow from the airflow. If the air is pull through then wash the opposite direction. If it's cycling on the low pressure switch then the indoor blower may be the problem, low on refrigerant, dirty filter, dirty coil.

It should be R-22

It should be a 42,000 BTU or 3 1/2 ton.

Its been a while since I worked on Coleman/Evcon units but if I remember correctly, the first 2 digits of the serial number is the month the unit was built and the next 2 digits is the year it was built and the rest of the number is how many were built.. For instance serial #11071025 it was built in the 11th month of 2007 and this was the 1,025th unit built.

Yes that is a Coleman

In the model number the 95 is the series of the unit and the 48 is the Btu's therefore you have 48,000 Btu's or 4 tons.

When the t'stat starts the furnace, 1st the draft inducer motor runs for a few seconds, then the igniter glows and the gas valve opens.The burner then lights, the igniter shuts off. If the burner shuts off when the igniter shuts off, then it's the flame sensor. 1st disconnect the power, remove the flame sensor and clean it with some 000 steel wool or scotch brite and reinstall it. 95% of the time that will fix it, otherwise you will need to replace the flame sensor.

you might want to check the filter, if the filter is restricting the airflow the furnace will over heat and it will shut down. if you turn it off and on it will reset it and it will try again. Pull the filter out half way and try that, if it runs fine then clean the filter or get a less restrictive one.
