Central a/c blows warm to hot air

Jun 30, 2009

- Yes it is. But its not warm/hot air all the time.
We turned it off for awhile then reset the thermostat. Started blowing cold air for a short time (5-10 minutes) then warm/hot air again.
We rent--the landlady will NOT pay to have it looked at, let alone have it fixed..
Glad the temps will be cooler this coming week in SE Mi..

Thanks for the reply..

- When I was on the phone with Hunter Fan, the service tech asked about the wires. I told him what color was where and he said that was good. I will have my husband check the wires on the furnace to make sure none are touching when we turn on the a/c Thanks so much for your help. I really appreciate you taking the time to respond.

- The furnace is a Williamson Temp-O-Matic. I can't find anymore info on it. Worked great last night after being off for a few days. Just tried it again and it started blowing cool air then after about 5 minutes, it started blowing warm air again. The furnace stays on after I switch to off on the thermostat. I had to turn it off at the switch on the furnace..

- some more info I found inside the furnace (very hard to read) Williamson gas-fired forced air furnace model 1114-10-6 style S 51 serial D 803 9052 (first three digits month and year) I also wrote down the wiring: 3 screws w/wires top row: left--- white and yellow middle-- blue (green?) right--- black and white 2 screws w/wires bottom row: left--- black and red right--red The white and the red wires on the left side screws come from one white wire. The yellow,blue,white and red on the other screws all come from a different white wire. The black wires look like a split-end power cord. I can't see where any are touching another wire.And I can't see any bare wire except around the screws. I sure hope you can understand my description. Thanks again for all your help.
