Hello,
I purchased a mobile home and kennel in rural Wisconsin and a recent electrical storm surge seems to have knocked out the cooling/heating system. After the storm, I checked the breakers and they were all normal, though I did reset them anyway, to be sure. I have also checked the circuits in the furnace and central AC with a volt meter and everything seems to be getting juice. If I set the thermostat way high or way low, nothing happens - no heat when set to heat and no AC when set to cool. To describe what is happening is to say that both the AC and Furnace are completely dead. They don't even try to come on and fail. Simply, nothing happens and I am very worried about this. I have checked and rechecked everything I know how to and am at a loss how to proceed.
Right now, the blower fan can only be turned on by going inside the furnace unit manually and it works if I flip the internal switch from auto to on. I also hit the furnace's limit reset button on the furnace numerous times with no luck.
As a single lady with low income, I am hoping to avoid calling a service man out to diagnose the problem for $150 just to look at it. I suspect that the circuit board or relays inside the furnace control panel may have been damaged, but how do I tell and can I change them myself if I can order the part from the manufacturer? I am not mechanical, but I can learn to diagnose problems and do simple repairs with guidance. Please help.
Furnace stats = 12 yr. old Intertherm; input - 70,000 BTU; output - 57,000 BTU; natural gas
Central AC stats = 12 yr. old Goodman model CK24-18 (don't know what else to tell you about it)
Thankfully, summers in northern Wisconsin are tolerable most of the time and I can live without the AC this season, but I do need heat in winter and if I need to replace the unit, I have to start saving and preparing now to get one in time for the cold season.

On many furnaces, on the circuit board, there is an automotive type fuse, usually either 3 or 5 amps. If your furnace has such a fuse check it & replace if blown. If you can't find a fuse, remove the thermostat & check for 24volts ac between terminals R & each of the other terminals. This must be done with the power to the furnace turned on. If no 24volts is present, I suspect a bad low voltage transformer.

Sorry Gyuri. This is a DIY site not a place to get work. Please read the rules.

Thanks Guys,
I don't recall seeing a fuse on the circuit board, but will check again. The voltage advice will also be used. My property is in far Northern Wisconsin in Oneida County. It might take a few days to do all the checking as I have houseguests through Sunday, but will give you an update when I have completed the checks in a few days.
