Illumination of the red light on the left side occurs in on-and-off intervals when cycling is occurring. Illumination of this light means that MidAmerican Energy has temporarily overridden the thermostat circuit of your air conditioner or air-source heat pump to signal your unit not to run. In the event of a power interruption, this red light also will come on for eight to 10 minutes after power is restored. The green light is solid or blinking at all times, as long as there is power to the unit. Light numbers 2, 3, 5 and 6 on gray devices are either not used or are used for servicing your unit and may be ignored.

SummerSaver troubleshooting checklist

Failure rates for air conditioner cycling devices are extremely low; however, we encourage you to call 800-437-2976 if you experience problems with operation or if you replace your air conditioner or air-source heat pump and need the device reconnected.

Here are a few items to check before reporting a device problem:

1. Is there electricity to other parts of your home?
If not, you may have a tripped breaker/fuse or there may be a power outage in your area. Besides checking your main breaker box, also check the outside disconnect switch to make sure it is in the on position. You may need to reset your disconnect switch by turning it off and then on again.

2. Check the temperature in the room to see if it is lower than the thermostat setting. This will cause the air conditioner not to run.

3. Check to confirm the thermostat is set on cool.

4. Is the indoor air conditioner blower fan operating?
The cycling device does not interrupt the air conditioner blower fan. If the fan isn’t operating, you may need to contact a heating and cooling contractor.

5. Has the air conditioner experienced a loss of power?
If so, the cycling device has a safety feature that prevents the unit from operating for eight to 10 minutes after power is restored. Illumination of the red light on the left side occurs during this period but does not indicate MidAmerican Energy is cycling. Also, some air conditioners have their own three- to five-minute delay. Please wait a full 15 minutes for operation of the unit to resume.

6. Are there lights glowing on the cycling device?
One green light should either be solid or blinking at all times as long as there is power to the unit. If not, you may have a tripped circuit breaker.

7. Is the air conditioner being cycled because it is a hot summer day?
If a SummerSaver event has been called, the red light on the left side will be lit when cycling. You can also check the main SummerSaver page to verify an event has been called that day.
