Turn system to "Fan Only" to thaw, then check outdoor condenser. Finding and Using the Official PDF Manual rheem model no rhqa 1220t pdf
The DIY community has documented some specific challenges when connecting the RHQA series to newer smart thermostats. Here are a few real-world scenarios to help you navigate the process:
: Represents the nominal cooling capacity of the coil. In Rheem's naming system, this aligns with a 1.0-ton to 1.5-ton system capacity depending on the paired outdoor condenser or heat pump. This public link is valid for 7 days
The most common failure point for an air handler is a restricted blower motor caused by a clogged air filter. A dirty filter makes the motor work harder, leading to overheating, electrical failure, and frozen evaporator coils. Check your filter monthly and replace it at least every three months.
For modern variants or units modified with newer digital controls, a diagnostic LED blinks specific error patterns on the master control board. If the blower motor won't turn on, or the circuit breaker continuously trips, check for loose connections, compromised run capacitors, or an open internal motor protector. If the system locks up, complete a power reset by turning off the breaker for 10 minutes to allow the control board memory to clear. RHQA - Rheem Replacement Parts Can’t copy the link right now
: Most 20 kW Rheem air handlers utilize two separate supply circuits.
