Is in series*

This question right here is a bit confusing since there is no calculation involved. But I know the current throughout the unit should be the same. I believe the main igniter and the boost are in parallel with each other and the safety isn’t serious since it travels just through line and through neutral. The detector switch to me looks like it could be some sort of switch or a shunt. I want to be the main and the booster at igniter are in parallel I would divide volt by 3 to get the resistance? Then use ED=I*R ?

[Clifford Fenelus]

Okay thanks got it.

[Clifford Fenelus]

The 120v we was reading was from L2 since they’re in phase with each other

[answer hidden] I just rewatched unit 6 video on a similar scenario

Are we going to reconnect L1 and then test voltage across the heater and L2 to determine if we’re getting voltage from that line?

[Clifford Fenelus]

I’m still trying to figure out part 2 of this question if we know that it’s an open circuit wouldn’t that be the issue? I read the questions over maybe I’m overthinking this heater test out good they said they disconnected L1 and 0vac on both line one and the heater but tested 120 vac on L2 it says the heater is good because it tested for continuity so we know there’s no break. A dryer needs 120 vac from both L1 and L2

[Clifford Fenelus]

Yes. Unit has a good power source so we should be getting on 120 from either side of the heating element, heat element needs to 240 to operate since current can’t go through the bimetal which created the open circuit

[Clifford Fenelus]

That would be a [answer hidden]

1. Assume that you have only done the measurements shown in Figure 1. What does the fact that you’re reading 0 vac ACROSS the heating element yet you’re measuring 120 vac FROM EACH SIDE of the element to Neutral indicate?

So if I’m reading 0 volts across the heater there is no current flowing through it.

[Clifford Fenelus]

Current is flowing in figure one because it has a close switch in the diagram which completes the circuits

[Clifford Fenelus]

So we’re getting zero volts because there is current moving through the unit so the problem is that l1 is missing?

[Clifford Fenelus]

They also says l1 is deliberately disconnected

[Clifford Fenelus]

0 volts means that’s there is a closed switch? I meant to say closed switch

[Clifford Fenelus]

Okay thank you
