Customer Question
I my heating elements aren't...
I my heating elements aren't coming on in my furnace. I checked the breakers in side of the furnace and one has current going to it and the other one doesn't. I thought the breaker was bad but I switched them and the breaker is good. There is no power going to the breaker.

My furnace blower will come on but no heat. I checked the breakers and one breaker has power and the other doesn't. I thought the breaker was bad but when I switched it there is still not power coming to it.I was wonder if the disconnect outside controls the heat also or just the a/c?
HVAC Technician: Steve Peck, Over 24 years experience Just Ask, quick HVAC repair! replied 7 months ago

It shouldn't

Ask Your Own HVAC Question

The power for both breakers should come from the breaker box.

Ask Your Own HVAC Question
Customer reply replied 7 months ago
one breaker has power and the other one shows zero when I check it with a voltage meter.
HVAC Technician: Steve Peck, Over 24 years experience Just Ask, quick HVAC repair! replied 7 months ago

Do you have something that looks like 4 breakers in furnace in a 2 and 2 pattern?

they are double pole breakers but just one switch. one is 60 and the other is 30

Perfect thanks, ***** ***** is evidently the one that has power, correct?

Ask Your Own HVAC Question
HVAC Technician: Steve Peck, Over 24 years experience Just Ask, quick HVAC repair! replied 7 months ago

Okay, the way they are setup is the 60 powers the fan and first set of elements and the 30 is for the other element.

it's not separate breakers, it looks like a double pole but it only has one switch

OK so lets test to common wire instead of ground, probably a black or blue wire that comes out by the others.

they have wire nuts on them, do I take them off and check?
HVAC Technician: Steve Peck, Over 24 years experience Just Ask, quick HVAC repair! replied 7 months ago

on the bottom of the the top sequencer. There is another white wire coming from a plug but the other end has a wire nut on it but it's not connected to anything. There is a red wire the same way.

that is where we should have a black or common wire going

on the opposite side of the switch.

Ask Your Own HVAC Question
Customer reply replied 7 months ago
when you say switch are you referring to the sequencer?
HVAC Technician: Steve Peck, Over 24 years experience Just Ask, quick HVAC repair! replied 7 months ago

Yes a 24v and a common will cause the heater to work on the bottom of the seq.

Ask Your Own HVAC Question

there is a black on the other side and a black and white on the other side

all of the other wires on the sequencer is black except for on the bottom one there is a blue wire
HVAC Technician: Steve Peck, Over 24 years experience Just Ask, quick HVAC repair! replied 7 months ago

ok so the tstat wire goes to one side, it is 24V when a call for heat so on the other side should be something going to common.

there is a red single wire and a white single wire that comes from a connector but the other end isn't connected to anything. It has a wire nut on it.

when I test the 2nd from the top and the bottom I get 12
HVAC Technician: Steve Peck, Over 24 years experience Just Ask, quick HVAC repair! replied 7 months ago

ok that is with no wires connected correct?

Ask Your Own HVAC Question
HVAC Technician: Steve Peck, Over 24 years experience Just Ask, quick HVAC repair! replied 7 months ago

Or is that to the case?

Ask Your Own HVAC Question
Customer reply replied 7 months ago
I get 12 with wires connected. When I test the top with no wires connected it stays at one when I test them together and when I test them to the case. When I check all elements with the case it stays at 1
HVAC Technician: Steve Peck, Over 24 years experience Just Ask, quick HVAC repair! replied 7 months ago

So 12 tells us closed or making connection and 1 is not shorted or connected. If element 1 reads 12 across terminals with no wires connected and 1 from each terminal to case, it is good.

Ask Your Own HVAC Question
Customer reply replied 7 months ago
