What Carrier Carrier® WeatherMaker® - 3 Ton Packaged Rooftop Cooling Only & Electric Heat Unit R-454B (460-3-60) alarm or error-code details should I share?

Confirm the thermostat or building schedule, whether one tenant space or multiple zones are affected, recent filter or maintenance history, and whether the RTU is locked out, noisy, short cycling, or not responding. Do not open rooftop panels or reset electrical equipment if it is unsafe.

A technician needs the full symptom and alarm context to diagnose it safely.

When is a Carrier® WeatherMaker® - 3 Ton Packaged Rooftop Cooling Only & Electric Heat Unit R-454B (460-3-60) issue urgent?

Treat the request as urgent when no heat or no cooling affects occupied space, an alarm or lockout is active, there is electrical odor, unusual noise, water intrusion, unsafe rooftop access, or repeated tenant comfort complaints. Include business hours and access notes when scheduling.

I needed a thermostat installed. I called one day they were there the next day. Installed the thermostat and made sure it was working before they left. Came back the next day because no heat was coming out the vents and fixed that issue. No problems since. Thanks...
