Intertherm MGHA-070ABFC-05 will not run/cool


Multiple problems. Eliminate thermostat first. Remove face from wall and turn on breaker. If fan still runs you have a bad board or bad relay. If fan outside is running compressor should be too. These operate on same contactor. Verify you are getting 24 volts to coil side of contactor. If odf stops working and contactor remains pulled in you have a bad motor. If odf motor stops working the compressor will shut off due to overheating.

Intertherm furnace burner comes on, but blower does not. If I turn thermostat off then back on until it clicks the fan will then come on. It does not do this all of the time, just now and then.


Furnace burner and heat element are not the same. I think the fan time delay, a sensor that turns the fan on when this sensor senses heat, is shot and needs replacing, for a furnace type heat ( gas heat)

Change thermostat


You have caught me without my old books, but I can tell you the orange wire is for the reversing valve on a heat pump. Almost all manufacturers, except for Lennox, are: R=Power (24volts), G=Indoor fan (Blower), Y=Cooling (A/C), and W=Heat. Some t'stat's are set up to use 2 separate transformers (24 volt), that is why you will see Rc, Rh. This is power for cooling and power for heating. If this is what you have, just take the Red wire and strip it back far enough to go under both screw terminals if the unit is a residential one. I've been doing commercial work for over 20 years and have never seen an "A" terminal, so I can't help you there. You may want to double check that. If I'm reading you correctly, I would put the orange wire on the "O" terminal. Don't understand why the "Y" terminal is not used. It turns on the compressor. The "O" goes to the reversing valve to "Tell" the outdoor unit that it is either in the cooling or heating mode.

Good Luck and let me know if I can help any further.

What's the deal? Wont shut off or respond to thermostat. . .


Red= power........White=heat.............Green=fan.................(grey)-(yellow)=cool .....these are the connectons. Disconnect these wires from the thermostat and know that red/power is the only wire that send power to the thermostat, and the rest sends it back to the unit to call for whatever,, red--to . white for heat... red to green for fan .... &red to grey for cool! OK! Turn all your power on, and use a jumper wire from red / green for fan and see if the fan comes on! Then move the jumper wire from red to green , to red / to white for heat and the fan , wait for 3 minutes before removing and going to the next step. Then red /to grey for cool and check if the outside comes on. Either you have a wire touching past the insulations and making a connection, a bad thermostat ,oe excessive wire lead touching the next connection.Thank you very much!

Intertherm heating


My heating unit is blowing cool air. The thermostat will start the blower when the unit is turned on at the thermostat, but the air isn't hot. But,when I turn the unit on at the furnace/blower using the "Fan On" button, I can see the heating element heat up. After the blower starts the heating element does out. What could be the problem?

Elec. intertherm FURNACE


It would help if I knew what type of system you have, lets start with the thermostat. If you disconnect the wires to it, does the heat turn off? I have seen thermostat wires pinched inside the wall, thus bypassing the thermostat controls altogether and it would run constantly. If you send a reply, tell the type. Wall furnace, central unit, heat & cool, gas, electric or heat pump. If you dont know tell me how many wires you have at the thermostat and the colors. You should know this, as you have changed it.

Intertherm to Honeywell thermostat


Typically if you have a yellow wire in the "y" terminal blue is used as common or "c". As far as your jumper from rc to rh, that will depend upon what type of heat you have. If all of your heat and cooling come from your packaged unit outside, yes you will need the jumper. If this does not work maybe you have a bad breaker or transfomer.
