Miguel T Riverview , FL August 29, 2014 Appliance: General Electric Microwave PVM2070SM4SS Unresponsive touchpad ge profile microwave oven 1. Searched and watched several videos online about microwave repair/troubleshooting (thanks videos from RepairClinic, ESRepair, Tomahawk DIY, ElectronicsNmore and a couple others). 2. Second: gathered the tools: a Philips screwdriver sizes 1 and 2, (optional) a drill with Philips bit size 2 (to speed up lowering of unit from cabinet), and a digital multimeter (with audible continuity, mine is an economic Craftsman M/N 82140). In all, you will end up unscrewing/screwing the 3 bolts (securing the unit to the cabinet) and removing/reinstalling 4 small screws! 3. With the knowledge culled from the videos and on the heels from my Samsung electric dryer (M/N DV520AEP/XAA) repair just two days earlier, (and USING ALL THE SECURITY PRECAUTIONS) first visually checked the control panel (thankfully no blown cap[acitors]s). 4. Then checked the 2 thermostats (there are a total of 4 named throughout the unit identified in the schematic - FYI, schematics are usually stored in the back or inside appliance cabinets by manufacturers) located immediately behind the control panel for continuity. Lo and behold, that identified as part no.16 THERMOSTAT (TCO) HOOD (40/70?) (104/158?) DE47-20020A WB27X10194 did NOT check for continuity. 5. Now, came the challenging part: figuring out the part no. online. Oddly, some online stores don't match part no. DE47-20020A with the M/N PVM2070SM4SS. 6. Once I decided to purchase the part, AppliancePartsPros.com made it too easy. 7. With the new thermostat on hand, all it took was securing the screw to the cabinet and reattaching the two blue cables. Read More...
