Iowans who want to register for a state appliance rebate program are having problems accessing the system. The Iowa Appliance Rebate Program was set to launch at 8 o’clock this morning, but users have been unable to log-on to the website or reach a phone number to claim their rebate.

An error message pops up when trying to access www.IowaApplianceRebate.com and a busy signal is heard when calling the toll-free number. The federal program is designed to help Iowans replace older, inefficient appliances with new Energy-Star models.

The mail-in rebates range from $100 to $500. The Iowa Office of Energy Independence is administering the program. A message on the agency’s website says the system is “temporarily down” because of an “overwhelming” response to the program. Iowans are encouraged to keep trying the website and phone number.

The toll-free phone number is 1-877-267-7495.
