see this causes and fix it. God bless youIf the furnace won't run, check the
electrical service panel
for a blown fuse or tripped breaker. Also make sure the power switch on
or near the furnace is turned on. Check the unit for a reset button and
try it. Some units have a built-in breaker or fuse panel.
If there is not enough heat, raise the thermostat setting five
degrees to see if it turns the unit on. If the unit still does not
generate enough heat, check the
comfort controls
. Clean or replace a dirty filter, clean the blower assembly (see the
Forced-Air Distribution Fix-It Guide), and make sure that all registers are open and not blocked.
If the furnace turns on and off repeatedly (cycles), clean or replace the filter; and clean the blower assembly (see
Forced-Air Distribution Fix-It Guide).
If the furnace is noisy, make sure access panels are mounted and
fastened securely; spray squeaking belts with fan-belt dressing and
replace worn or damaged belts; adjust the blower belt; lubricate
motor and blower oil ports.
If the element does not heat, refer to the
Heating Element Fix-It Guide for guidance.
