Coleman 7330 Wall Thermostat Model State Prep

Use this Coleman-Mach thermostat document to record 7330 thermostat face, mode, and response details before service.

Owner-safe checklist

• Record the 7330 thermostat model, heat/cool/fan selections, temperature setting, response from each normal owner-facing switch, and coach equipment served by the thermostat.
• Save photos of the thermostat face, model markings, owner paperwork, and current mode settings from normal owner access.
• Do not replace, reconfigure, or service the thermostat yourself; contact Coleman-Mach support or qualified RV HVAC service for no response or repeated control failure.
