Question about Intertherm Heating & Cooling
I am getting a flash code 1 that the limit switch is open but I don't know where the limit switch is or how to troubleshoot/replace it.

It would be a safety switch up by blower assembly. typically has red reset button.

how often do you replace your filter?
On the limit switch that protects your unit when it gets to hot the number one reason is dirty filter.
The pressure switch is located in the upper side of cabinet has a rubber hose connected to it. They very rarely go out though. So find your vent fan the first fan that comes on and follow the rubber hose to the switch.

Sounds like you took a hit from a capacitor. That is the only thing that could Zap you if you are sure all power is off. Usually capacitors hold a charge if their is no resistor/ bleeder on it. Find your capacitor(s) round or oval with wires coming off the top. DISCONECT POWER TO UNIT. Short across the terminals on all capacitors with a screw driver to release charge. Do not touch metal part of screw driver while doing this. Then remove your wires form your limit with insulated insulated needle nose pliers.

SOURCE: i have a intertherm furnace
Hello, a limit switch will open for the following reasons, dirty plugged filter, blower motor not operating on correct speed or weak, too high gas pressure to burners. If you have a thermometer you can check the temp rise of the furnace by measuring the return air temp and the supply air temp and then the differance between the two numbers will give you your temp rise, compare it to the temp rise that is stated on the furncae data plate. if you are not in the range of what the data plate states then start with the filter and check the blower motor to make sure it is operating correctly.
