I'm looking at adding a resistor or bulb inside an Acorn stair lift motor housing to keep the temperature about 40degF. The unit is in an unheated area and temps get too low for the motor to turn normally. I considered an electric blanket or pad but having an elderly person messing with something on the stairs is not a good idea. Also, there's the issue of having a separate part and cord to deal with.

Cheat this out and see what you think. I have done this when setting up electronic devices in remote locations, installed in an insulated box with a car battery & resistor. In this case a night light bulb might be another choice.

Is the motor under the stair? How is the power
supplied to the motor? Makes me wonder if you
can use the existing wiring some how.

Are you able to contact the manufacturer? Maybe
they have a low ambient temperature kit. Why
reinvent the heater wheel?
