電気ストーブ900ワットのサーモスタット不良でこの部品交換で修理完了しました。メーカーでの修理は部品が無くて出来ないとの事だったので助かりました。

早速使用してみましたが、最初の1個が動作不良でした。NCなので通常温度でONなのですが、定格温度115℃になって、パチンとバイメタルの動作音がするのですが、導通したままです。OFFになりません。おかげて温度ヒューズを破損してしまいました。最大電流20Aまでの規格ですが11Aヒーターなので過負荷な訳ではありません。次の1個は今のところ正常なようです。残りの2個の動作も不安です。取り付け前に動作確認が必要です。4個1組の販売なので1個だけ返品する訳にもいかないですよね。1個だけ交換してくれればうれしいのですが・・・・。
