Weil McLain indirect water aquastat

Hi everyone,
ive got a WM indirect water heater that goes through aqua stats like crazy. Is there a reliable aftermarket one I can use instead?

Aquastat

They quit working intermittently or altogether. The only way to generate hot water is to put a jumper on the thermostat wires. When it first acts up turning the temperature knob up and down will sometimes get the circulator started. Research tells me its a flaw with this part.

Hi, looks like you are stuck with that one WM has had lots of problems with that whole unit, even a class action law suit, maybe you should contact them.

Yeah, were in that already. First complete tank replaced within 11 months and one thermostat in another 6 months. Three more since. Thanks for your help.
