Why Scene does not open after scene fading? C#

My Scene does not open, but it goes to black screen (middle of the fading)?
I tested this with out fading and it worked and went to the losing scene.

using UnityEngine;
using System.Collections;
using UnityEngine.SceneManagement;

public class loseParticle : MonoBehaviour {

	public GameObject explosionPrefab;

	void OnTriggerEnter2D(Collider2D obj) {
		GameObject explosionObject = Instantiate(explosionPrefab, this.transform.position, Quaternion.identity) as GameObject;
		Destroy (explosionObject, 5f);
		Destroy (obj.gameObject);
		IEnumerator ChangeLevel () {
		float fadeTime = GameObject.Find("_GM").GetComponent<Fading>().BeginFade(1);
		yield return new WaitForSeconds(fadeTime);

I have found a way it took long… So if someone has same broblem. You can ask me now :smiley:
It didn’t load because i deleted the object that the script was attached to. thanks for your time all who helped or tried to help.
