Replacing Myson Toe Kick Heater

I have a Myson toe kick heater under our kitchen sink that seems to be malfunctioning. I believe it has to be replaced since it is barely working. I am not a plumber and it appears to be attached to our hydronic heating pipes. I presume that this is something that a local plumber can replace and install for me? Any words of wisdom with regards to brands and/or sizing of the unit? What about if I should consider repairing the existing unit which just seems to be having a difficult time with the fan turning the motor to push out the hot air? see photos of the unit attached. Thanks! Michael

    So I think that it may just need to have the limit switch replaced. Otherwise, I'll have to replace the fan/motor and then the entire unit. That's what Myson told me. Any other thoughts? Any local contractors near 10706 available to assist?

    Thanks very much. Is it worth actually paying to replace the whole unit (getting contractor to drain system, remove and install whole new unit), or finding someone to help me replace the limit switch? If the latter, would an electrician be able to replace the limit switch?

    The switch is set up so that it turns on the fan whenever the pipe is hot. Usually if the fan will not work, either the pipe is not hot due to a lack of water flow or the switch is bad.
    Are the pipes hot?

    Pipes are hot but fan won't turn. However, I tried to replace the limit switch myself and couldn't figure it out (I am a consumer). Should I get an electrician to come try to fix it?

    I could be an electrician, heating guy or appliance repairman.
    The quick way to check is to jumper the switch (connect the two wires) and see if the fan works.
    It will be 120 volt, so if you are not comfortable you should call a professional.

    We replace alot of those fan/motor assemblies. Very easy to do provided there's is access. (Usually 2 wing nuts I think)

    Got power? Before you replace the fan switch make sure the unit has power.
