10 mpA 277 VAC
22 Amp 125,250 VAC
Double Line Break
Mears Control

I need to replace this thermostat. The brackets for the spindle  connected to the control dial (Off to 9) are broken. The dial does not turn properly. Where can I find a replacement? Went to MOR Electric Heating site, but Model numbers don't seem to match with anything on my thermostat.


If this is a standard line voltage thermostat suggest grainier.com ,  you would need to check to see if your Mead stat is single pole single throw or double pole double throw . The info you provided says double throw . A line voltage stat brand is not important , the amp. Rating is . And switching mechanism. Grainier is a nationwide company that sells to the public needing only an account setup.
