    Intertherm mmha-070abhr-05 blower motor won't shut off
    Furnace cycles fine but blower will not turn off. I checked on some possible answers online and found it may have something to do with limiter switch, the problem is I cannot find a limiter switch on this furnace. Blower on top, attached to front is a box that has wires coming from thermostat, below that is a switch that has on/off/fan. I removed a few panels and cannot find what should be the switch.

    If the furnace fires, the problem is not the limit. You most likely have a sticking fan relay.
