I have a Horizon CT 5.4 treadmill I bought in 2014. I used it occasionally and it was working fine. The only odd thing about it was that everytime I turned it finished a workout or turned it on it displayed a "lube Belt" message but hitting any key made it disappear. I also lubricated the deck quite frequently. I recently turned it back on again after some 1 year of inactivity but this time the lube belt message did not go away. I lubricated the deck, dusted it off, reconnected wires, tried all the key combinations ( speed + & STOP for 10 secs, elev + & speed - for 10 secs) but nothing is registering on the computer. No new menu opens, its just that message stuck there. Been doing this for two days. Do i need a new controller or control panel? I dont know any technical stuff and purchasing these components is expensive, so I want to exhaust all other options first. Any help would be appreciated?
