Coleman 7330D Digital Thermostat Face Prep

Use this Coleman-Mach 7330D thermostat document to identify the digital thermostat face and record mode behavior before support.

Owner-safe checklist

• Record the 7330D thermostat model, face marking such as 7330D3371 or 7330D3381, selected mode, fan state, temperature setting, and response from normal owner-facing controls.
• Save photos of the thermostat face, model markings, display state, 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.
