Abstract
An icemaker control circuit may include an icemaker module and a DC motor. The icemaker module may include a control board that receives an AC power signal directly from an AC source that is external to the icemaker control circuit. The module may also include self-contained electronics and controls that allows icemaker operation without a need to interface to any signals other than AC power signal. The DC motor is provided for moving an output drive and is controlled by a DC output of the control circuit of the icemaker module in response to applying the AC signal to the icemaker module.
Claims15
A refrigerator comprising:
- an icemaker module comprising a control board that receives an AC power signal directly from an AC source that is external to the refrigerator, wherein the AC power signal is a high or low DC reference point for a control circuit, and wherein the module comprises self-contained electronics and controls that allows icemaker operation without a need to interface to any signals other than AC power signal;
- and
- a DC motor for moving an output drive, the DC motor being controlled by a DC output of the control circuit of the icemaker module in response to applying the AC power signal to the icemaker module.
An icemaker control circuit comprising:
- an icemaker module comprising a control board that receives an AC power signal directly from an AC source that is external to the icemaker control circuit, and wherein the module comprises self-contained electronics and controls that allows icemaker operation without a need to interface to any signals other than AC power signal;
- and
- a DC motor for moving an output drive, the DC motor being controlled by a DC output of the control circuit of the icemaker module in response to applying the AC signal to the icemaker module.
A method comprising:
- providing an icemaker module and a DC motor;
- receiving, at the icemaker module, an AC power signal directly from an AC source that is external to the icemaker module, and wherein the module comprises self-contained electronics and controls that allows icemaker operation without a need to interface to any signals other than AC power signal;
- and
- outputting, from the icemaker module, a DC output to the DC motor for moving an output drive in response to applying the AC signal to the icemaker module.
