Question about Heating & Cooling
My lennox furnance GCS16R-411-100-5P all of a sudden wont kick on . we changed the thermostate and still nothing. the blower will kick on if I switch it to auto but blows out cold air. We can hear something in the unite but it won't do anything. does anyone know what it could be ?
you may need to remove the rear cover to examine what is and is not running. once you remove the back, start up the unit on a workbench. see if the fan is running and the compressor has kicked in. look at the larger or two tubes coming out of the compressor. if it is cooling a small layer of frost or condensation will appear on this " suction" line. if this tubing and the other one are approx the same temperature, then there is a freon leak in the system. Only an EPA certified technician can fill your unit. I am not familiar with that RED button but it mat be a reset of some sort. With the back removed see how it is connected in the wiring circuit. if you have the wiring diagram, please send it to me under my regular email address and I'll walk you through the troubleshooting procedure.

water should never reach the nipple for the pressure switch tubing on the IDM. Check the entire condensate drain system for obstructions. Verify water makes it from the furnace location to the outside drain. Flush p-traps and any anti-siphon devices thoroughly.

your fan motor outside is going bad, have a service company change it out for you.
the motor stopped working and that overheated the compressor shutting it down on thermal cutout, and it will only come on once it cools down

SOURCE: Will not cool properly.
You have either a faulty thermostat, dirty condenser and evaporator or a faulty run capacitor. Need to service soon before the compressor is damaged. Sea Breeze
