But opting out of some of these cookies may affect your browsing experience. For this repair you will need a Phillips screwdriver, a 15 or 25 watt soldering iron, a desoldering tool (recommended), and four electrolytic capacitors. The information that you have been getting on voltage is absolutely wrong and is simply HEARSAY. MITSUBISHI MR SLIM P SERIES (A) ERROR CODE: A0 CENTRAL CONTROLLER: 6600 PROBLEM WITH AC UNIT: Duplicate address – Lossnay units attached with the same address – change addresses and reset the units power. Remove the plastic panel mounting screws and set the panel aside. Indoor unit does not support wireless receiver. The DM guide partly covers the capacitors that need cooling and the metal tray under the CRTs also restricts fan placement. During COOL and DRY operations, pipe or pipe connecting sections are cooled and this causes water to condense. It is defined as VS-74 of October 2007. The sensor might be at fault. As you will read below, doing the repair yourself will cost less than $4.00 for the 4 Caps. If you hold the DM with the components facing you and the external connectors on the left, you can find the capacitors in question in a cluster on the top right corner of the board. Check out a data sheet such as: In the heating operation, water condensed on the heat exchanger drips down. The picture below shows the underside of the DM board after the capacitors have been removed. Are available in the Panasonic FM Series, Mitsubishi Television Error Code Diagnostic Procedure.
