My home A/C stopped working the other day. I set my thermostat to cool and nothing set it to heat and raised the tempt. on the therm. and nothing as well. I set the fan switch to on and nothing also.

All my breakers are on and I am getting 220v after my fuses and also at the contactor. I pressed the contacting points on the contactor on the condesor unit and the fan worked. I also changed my thermostat and still nothing.

PLEASE HELP Its getting to hot for my 3 week old son

Check to see if there is a small fuse on the circuit board on the inside unit. Sometimes the 24 volt supply is fused. Post back with your findings and it would be nice to know the unit brand and the model number for the inside unit.

I got the model number of my air conditioner and it is a Rheem Air conditioner Model # RAJA-036JAS. And the Inside unit is a Honeywell Air Cleaner F52C. I checked for voltage going into the inside unite and I have 110v ac.

Hope you can help

I believe you have a 24 volt low voltage problem. Check for a small fuse as was mentioned before. Then start to track down the 24 volt control circuit. Since your indoor blower will not come on and you have all the other voltages necessary for operation I am pretty sure it is in the low voltage power supply area or low voltage wiring. Look on the blower door for a wiring diagram so you can follow it and test for low voltage. I would start at the transformer and work forward from there.

If you are not capable or fail to find the problem I suggest you call for professional ON SITE help. You mentioned that you have a new born and if that is the case and you feel that the heat is a real problem I would check it out asap and if it is beyond you call for ON SITE service right away.
