Easiest method of diagnosis is to remove / replace component one at a =
time until the problem is eliminated. In this case, turn off the =
breaker, remove the thermostat and connect the line and load wires =
together. Turn on the breaker and see if you get heat. Still no heat, =
then you have likely have a bad heater. Assuming the breaker is =
functioning properly. If there are other heaters on the came circuit =
you can assume it's not the breaker.
My elec. baseboard unit is barely putting out any heat. The =
thermostat is original to the house 30 years ago. It is a Honeywell =
T498A All connections at the stat are tight and voltage coming in is =
OK. Has the thermostat has gone bad? What is the likely. Thanks =
for any input. problem? The thermostat is only about $24.00
