BATH — Four months after Gediman’s Appliance abruptly closed its Bath and Lewiston stores, prompting dozens of customers to complain to the state Attorney General’s Office about goods or services they were owed, more than 300 floor model refrigerators, ovens, washing machines and other appliances will be sold at auction beginning Friday.

According to Keenan Auction, online bidding begins at 9 a.m. Friday and continues until 1 p.m. Monday, Feb. 2. A “preview” of the merchandise is scheduled Friday, Jan. 30, for 11 a.m. to noon at the former Bath store, and 1 to 2 p.m. at the former Lewiston store.

In early September, Gediman’s Appliance on Centre Street in Bath closed without notice after 86 years in business. Gediman’s on Lisbon Street in Lewiston also closed that month.

Dozens of customers contacted the Attorney General’s Office to say that Gediman’s owed them appliances, repairs or — at the very least — their money back, complaint examiner Martha Currier of the Attorney General’s Consumer Protection Division said in October. Many of those customers continue to await a resolution to their complaints, some of which involved thousands of dollars and were for appliances that were included in construction contracts.

Heather Kindell-Leeman of New Harbor, who co-owns Christopher Leeman Building Construction with her husband, Christopher Leeman, said Wednesday that she still hasn’t heard a word from business owner Peter Gagnon or the Attorney General’s Office about the $6,000 Blue Star oven she paid for but never received.

“Not a word,” she said. “It’s beyond frustrating, and there are a lot of people out a lot of money.”

Attorney Leonard Sharon, who represents Gagnon, said in December that Gagnon “bit off more than he could chew” when he opened the second store. He said Gagnon never took money without intending to provide goods or services, and that Gagnon was actively seeking financing to continue the business up to and even after it closed.

Currier said in October that she was notified by Gagnon’s attorney that the store owner planned to file for bankruptcy.

In an Oct. 7 letter to complainants, she wrote that because secured creditors — banks and businesses — are considered first to receive redress in a bankruptcy, it was unlikely customers would receive a full refund.

As of 10 a.m. Wednesday, neither Gediman’s nor Gagnon had filed for bankruptcy, according to the online court document system.

Sharon had not responded to an email or phone call seeking comment as of 10:30 a.m. Wednesday.
