Intertherm P3RA-048K Air Conditioner - Answered Questions & Fixed issues
I have an old Intertherm gas-fired furnace, Model
Tom P's answer is generally correct: The motor start capacitor is usually not the problem. However, in some cases, particularly on older furnaces, where there were capacitors of certain make and production run will prematurely fail. This happened in March on a mobile home HVAC unit where both the blower fan and condenser fan motor capacitors failed open circuit. Both caps were of the same Mfg, and production lot.
Here is a suggestion (for you or an electrically inclined friend): Locate a substitute motor capacitor having similar Mfd (or MF) and Voltage ratings. Remove power from the unit. Reach into the blower squirrel cage and spin it to verify that the shaft is not frozen. Pull the wires from the existing capacitor noting color and location. Connect the wires to the substitute capacitor and secure it place. Apply power and turn on the blower. A no start? Motor replacement time.

Intertherm/nordyne furnace (24 years old)
Shut off power, get a small wrench, remove orifice spuds and clean them with toothpick. Take burners out and clean rust from them. Check and see if you are getting 24 volts to gas valve. If not replace it.

Intertherm heat pump blows hot then cold then hot
You may have a problem with a temperature safety system. Before changing anything else, check to see if the unit is clean!!! Dirt/dust can fool the safety system into an overtemperature status. Inspect the heat coils for damage and dirt. Gently clean.

Intertherm furnace M1BG wont fire
Make sure the gas valve is turned to the ON position after you had it in PILOT position. Also check the thermostat low voltage wiring @ furnace...jumper the Red & White wires to bypass the thermostat temporarily. Make sure there is 24 volts on you low voltage circuit.

My intertherm furnace blower stops coming on. If I
Turn the power off to the unit and use a different color thermostat wire in place of the green wire. If this works, there is a short in the wire. If not it's likely either a relay or a bad motor.
