Please note: please open up the remote control and verify that the frequency written on the quartz inside is 40.685 MHz. If the frequency is 27.015 MHz, then please choose the MAHS27-01. If your remote control has a frequency of 27.045 MHz, then there is no replacement for it. You will need to install an upgrade kit. If your current remote control has 12 programmable switches inside, then you only have to set the last two switches (11 and 12) to OFF both inside the current remote control and inside the receiver.
