C# Door Script Problem

Hi. I made 2 animations with door open and close.

Use raycast to identify the distance with door -> The ray hits the door -> If bool door is not true -> if you press E -> Play door opening animation

It doesn't have any problem with raycasting and bool... But I think there is problem with my animation. I want my script using animations not "animator".

Here is my script

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Doors : MonoBehaviour {
 
     public Animation doorOpen;
     public Animation doorClose;
     bool isOpened;
 
 
     void Start()
     {
         doorOpen = GetComponent<Animation> ();
         doorClose = GetComponent<Animation> ();
         isOpened = false;
     }
 
     void Update ()
     {
         RaycastHit TheHit;
 
         if (Physics.Raycast (transform.position, transform.TransformDirection (Vector3.forward), out TheHit, 30.0f)) {
             if (TheHit.collider.CompareTag ("Door")) {
                 if (!isOpened) {
                     if (Input.GetKeyDown (KeyCode.E)) {
                         doorOpen.Play ("Door_Open");
                     }
                 }
 
                 if (isOpened) {
                     if (Input.GetKeyDown (KeyCode.E)) {
                         doorClose.Play ("Door_Close");
                     }
                 }
             }
         }
     }
 }

Please fix the script for me. Maybe I made a mistake on Raycasting too.. I'm not sure. Thanks
