When your Panasonic air conditioner displays the H11 error code, it is indicating a communication error between the indoor and outdoor sub-units. An H11 error on a Panasonic AC points to an electrical or physical fault in the wiring or the wiring contact points to their mainboard terminals on either the indoor PCB or outdoor PCB. It can also mean your air conditioning unit is low on refrigerant gas and needs to be refilled by an aircon service technician.

Troubleshooting the Panasonic aircon H11 error involves a thorough maintenance check and inspection of the internal wiring system of your indoor unit as well as that of the outdoor sub-unit, which should be in an open, well-ventilated area at all times–a clearcut directive that won’t be an issue for HDB flat owners who consistently applied the Building and Construction Authority’s specifications on aircon installation and maintenance. Also, any sweetish ether-like odor of refrigerant gas might indicate a leak in the piping system, which could be the reason for the low levels of coolant gas and H11 error code showing up on the AC display; and if this is the case, seek professional assistance immediately.
Silverback Aircon has a collection of well-maintained, expertly tested and refurbished Panasonic aircon spare parts on hand. We can promptly replace any damaged indoor PCB or outdoor PCB that might be behind the H11 error. Here are the estimated prices for replacing those parts.
Note that in case we discover that a failing outdoor PCB is the source of the F95 fault, we will not simply replace a defective PCB or two. Silverback Aircon will install the whole circuit box with the complete set of PCBs corresponding to the model of your condenser unit. For the Panasonic CU3S27MKZ condenser model, there are three types of PCBs–the control board, power board, and noise filter. For the Panasonic condenser model CSS9PKZW, only two PCBs–the control board and power board–are used.
The following table shows aircon servicing through Silverback Aircon, in case your Panasonic aircon F95 error is caused by the lack of proper maintenance. Silverback Aircon’s full aircon servicing job includes cleaning of the AC cover, expert washing of the aircon filter, clearing of drainage pan choke, vacuum cleaning of the evaporator coil, and reinstallation of the aircon’s back cover. Also included is a gas leak check, if it’s applicable.
