2 Pcs SFK-112DM 20A/250VAC Relay Module

When you add a low voltage DC current (fraction of an amp @ ~12V) to the one set of pins on the bottom, the switch will close, allowing AC current (rated to 250V; obviously can be used with 120V appliances) through the contacts. The large contacts on top pair with the other set of contacts on the bottom.My dehumidifier, which had been a workhorse for years, had been making this weird noise and I realized that the compressor was staying on even after the fan had turned off. Just had to replace the old matching relay on the board with this one and everything is as good as new (taking it apart was a pain, but it needed a good interior cleaning anyway). I read that lots of dehumidifiers break after a year or so, so I figured the one I had was a gem and didn't want to replace it.From my research, it seems that this same part is used in lots of different dehumidifiers and small AC units. If you're having a problem similar to what I had, I'd test that relay as a first course of action.

I had an air conditioner which had an issue where the compressor would stay running regardless of the AC being powered on or off. I had an option to change the board itself and was able to find this relay by searching the part number on Amazon. I was comfortable with soldering and was able to use this to repair rather than replace the board.

Purchased to repair my 70Pint dehumidifier. Works perfectly and dehumidifier continues to work after 6+ months of use.

Worked perfect. The sad thing is that LG and Friedrich ACs come with this relay. One unit has gone through two of these in less than two years.

Fixed my GE dehumidifier.
