Problem Statement: A power assist chair (that we purchased for my mother back in 2016 and no longer need, looking to sell used) had an intermittent – the up/down LED lamps would go out, and the chair would not operate, until one jiggled the power cord.
Annoyance #1: Called the manufacturer to get a replacement cord (I had troubleshot it down the cord itself). Turns out the cord is hard-wired into the motor, so the solution is to replace the motor. (bad answer, the motor itself is fine). Why is a simple power cord that will invariably get a bit of wear and tear not be easily replaceable?
Annoyance #2: Yes, it’s under warranty, but it requires both a service call (to replace the motor) and shipping charges. Um, no.
Annoyance #3: Additionally troubleshot the cable and discovered the intermittent was in a little inline molded box containing an LED, the sole purpose of which (as far as I can see) is as a redundant and unnecessary troubleshooting tool – since both the chair control pendant and the transformer also have LEDs to indicate power on.
Solution: Cut the molded box LED out, strip and splice the cable (nicely soldered and insulated), it’s a wee bit kludgy with electrical tape, but perfectly safe and solid). Took about 15 minutes including time to heat up the soldering iron and then test the crap out of it afterwards.
Ultracomfort America – not impressed.
