Why does this keep turning the orientation back to 0?

So I have a gate script which works all good, but for some reason, When I click the gate, it moves up, but turns it into the orientation of 0, we need the orientation to 0,90,0. So we did that after each tween played. But still when we click it, it turns it back to 0 orientation. Here is the server script:

local TweenService = game:GetService("TweenService")
local door1 = script.Parent.Parent.Part1
local tweeningInformation = TweenInfo.new(
    2,   
    Enum.EasingStyle.Linear,
    Enum.EasingDirection.Out,
    0,
    false,
    0
)
local door1Open = {CFrame = CFrame.new(-161.498, 15.143, -125.72)}
local door1Close = {CFrame = CFrame.new(-161.498, 5.666, -125.72)}
local tween1open = TweenService:Create(door1,tweeningInformation,door1Open)
local tween1close = TweenService:Create(door1,tweeningInformation,door1Close)
 local open = false
script.Parent.ClickDetector.MouseClick:Connect(function()
    if not open then 
    open = true
    tween1open:Play()
door1.Orientation = Vector3.new(0,90,0)
    else
    tween1close:Play()
door1.Orientation = Vector3.new(0,90,0)
open = false
    end
end)
