Trivial question about indoor/outdoor RF thermometer behavior.

I've some brand x thermometer RF receiver with three channels. It picks up three temperature reading from somewhere in the neighborhood. The temperatures are close to what one would expect. I don't know where any of the transmitter are located, just somewhere in the neighborhood.

This morning I got the expected temperatures near 30F on channels two and three but channel one reported 13F. Could someone have moved their transmitter to their freezer and it still transmit? Can a transmitter go bezerk? There is a mountain about 12 miles away. The transmitter will not transmit that far will it?

I'd think the metal shell of a refrigerator would interfere with the signal. Maybe that sensor has a bad battery. Is it possible that two are in the sun and one in the shade?

All channels are back to reading nearly the same this morning. Yesterdays reported readings were before sunrise. Someone could have changed a battery I suppose. I've only this old receiver. I don't know where the transmitters are located.
