Question about Microwave Ovens
Good day sir/ma,am there are possibilities that the roach spray solution got on the contact terminals. DO NOT Turn it on, let it dry for several days. just to make sure. 3 days is enough. or if you choose to operate it, you must clean dry the circuit board. it requires that you dismantle it, clean the terminals dry and reassemble it again. this may not sound good. you may need to call your service center to be safe. hope this helps.
