The outside unit will not defrost and a thick layer of frost will build up, rendering it innefective.
Assuming you are talking about a heatpump... Defective defrost timer board or thermostat.
do you have a heatpump or a/c? if it is a heat pump you can,that is what happens when the system goes in to the defrost mode. if its freezing you could be low on charge or or bad defroster board or even worst a bad reverseing valve.
my 1998 gmc jimmy has no floor heat but i have defrost and ven heat
The operation of the electric defrost heater and the hot gas solenoid is typically controlled by the defrost timer or a defrost control board in refrigeration systems. These components regulate the timing and activation of the defrost cycle, determining when to heat the evaporator coils to remove frost buildup. In some systems, a thermostat may also play a role by monitoring the temperature and signaling when defrosting is necessary.
The defrost timer, thermostat or logic board, whichever you have is probably bad. To quickly remove the ice build up on the outdoor unit switch it to run the ac for a few minutes or until the ice clears.
no heat to front window went defrost is on
It can, but for safety call or check with the banned that you have
goes slower
ihave a 1986 chevette that when i turn defrost on it blows out heat and when i put heater on it blows out only cold air? ihave a 1986 chevette that when i turn defrost on it blows out heat and when i put heater on it blows out only cold air?
If it's stuck open, no heat. If it's stuck closed, over heat.
a heat sensor
The density of a fluid goes down (becomes less dense) when heat is applied.
