I have a Bryant thermostat X4147 and a Lennox Elite

Customer Question

Dear Sir: I have a Bryant thermostat X4147 and a Lennox Elite heat pump S/N:5809M06337. The light on the thermostat went out. I replaced the batteries
after pulling off the front of the unit, but that didn't work. Can I get the light to come back on?
